Hi,
As per suggestion I built the code from https://github.com/ArcticaProject/nx-libs. And I still run into the same issue.
Does anybody here know that part of the code (snippet in the report)?

Please take a look at [1] and make sure either of those paths exists
on your system.
You need the fixed fonts in the misc/ fontdir.
Is everything in place there?

The folder /usr/X11R6 hasn't existed on Gentoo for years now (since move to Xorg). Does the folder /usr/X11R6/lib/X11/fonts exist on other distros?
Also, the code seems to be making an attempt to look for "ALTERNATE" font paths and many of those paths are there:

I don't think its a font path problem. The font paths can be specified at the command line with -fp /<path1>/,/<path2/,... and it loads all fonts fine, including the "fixed" ones from /usr/share/fonts/misc/ folder specified on the command line and the ALTERNATE paths specified in the code.
If I change the font with -fn to "9x15" to be the default font, it still fails to open the default font "9x15". I know for a fact that 9x15 font exists in the custom paths I have specified using -fp.
So, its not a font path issue. Its what happens when it wants to set the default font and calls those 2 functions. Most likely, the second function is the one which is failing because the fist function has failure cases only for allocation failures.

You can us the -fp option of nxagent/x2goagent to pass an arbitrary font path. Furthermore you could set up an heuristic that determines valid font paths. For our company internal script we use this (ugly) code:

I thought I mentioned it. I tried both -fp and -fn arguments to influence the behavior of nxagent but it still failed with the message saying "could not open default font '<whatever font used with -fn>'"
The font specified with -fn exists in font path specified with -fp.

this is so weird... Hmmm... I don't have the time to spin up a Gentoo
right now. Please try to reach the other Gentoo people on IRC (there
are several users on IRC from time to time using Gentoo), maybe any of
them has a clue. I definitely know (i.e., have heard) that X2Go with
nx-libs is working on Gentoo for others.

Definitely working for me and others.
I think the fonts message is a red herring and not the real cause of trouble. I have checked Debian and Fedora systems, too, and they likewise don't have a "fixed" fonts directory.
Given that I cannot reproduce it, it's likely a problem with his specific system, so reproducing and debugging is difficult on my end.

Definitely working for me and others.
One of the strange things about my setup is that its /usr is read-only (like on a livecd). That's the only thing I know is different from a regular gentoo system. Do you think that's something that might cause issues?
Technically, nothing should be writing to /usr.
The setup is basically booting a squashfs image (same image boots on 10 different desktops and laptops I have) just like a Gentoo livecd and has writable folders in / (tmpfs) for everything except /usr, /bin, /sbin, /lib64, /lib32. Their /home is on a local disk on ZFS (mostly) or ext4. This is done mostly to avoid maintaining 10 different systems. I create a new image once in a while, these systems pull it and it gets picked up on their next reboot. Many of these systems haven't booted in quite some time. As long as I don't need an update (a new package I can't live without or fixes for known exploits), they keep going.
Does this ring any bells with respect to this issue?
I think I agree with the conclusion that 'fixed' font thingy is a red-herring.

That's differing from my setup for sure, but I wouldn't know nx-libs writing anything to /usr, so I don't think that's the problem.
Have you actually looked at *all* output by nxagent?

Yes, I have looked at all of session.log. I am cutting and pasting it here, in case I missed something:

I find something odd about this error message.
It doesn't seem to be coming from nx-libs.
Note how the code in nx-libs spells "could" in lowercase, but the message spells it with a capital letter.
I'm using nx-libs without any problems on a system having =x11-libs/libXfont-1.5.1.
Please try to make sure that the following packages are all installed (and correctly installed! If in doubt, reinstall):
media-fonts/font-alias media-fonts/font-arabic-misc media-fonts/font-cursor-misc media-fonts/font-daewoo-misc media-fonts/font-dec-misc media-fonts/font-isas-misc media-fonts/font-jis-misc media-fonts/font-micro-misc media-fonts/font-misc-misc media-fonts/font-mutt-misc media-fonts/font-schumacher-misc media-fonts/font-sony-misc media-fonts/font-sun-misc
Next thing to consider is your DPI. Do you use any "weird" DPI value? I don't think that's it either, but try setting it to 75 or 95 for testing purposes.
How proficient are you with debugging? Or is there any way to allow access to one affected machine? I'd like to get a gdb backtrace of the moment the FatalError() function triggers, to see which library or part *really* is responsible for that message. This will also involve building nx-libs with debug symbols, of course.
Mihai
One more thing Mike#2 just mentioned on IRC and I have confirmed not to be the case in Gentoo: fontconfig is not a dependency of x2goserver, though it should be.
Actually, it probably should be a dependency of net-misc/nx in general and not x2goserver, but let's ignore that "issue" for now.
Is media-libs/fontconfig installed on your system? If not, do that, rinse, repeat... and try the other stuff in my former eMail.
Mihai
Note how the code in nx-libs spells "could" in lowercase, but the message spells it with a capital letter.
I was thrown off by that for a while. It took me a while to search that message because I was searching for exact message and it wouldn't find it. When I did find the message and then looked at the wrapper function that was being called with that message, I knew what was going on. The wrapper pretty prints the enclosed message by capitalizing the first letter....one of those genius ideas. Wasting developer time since the dawn of the times.
Anyway, the fontconfig is definitely installed (KDE wouldn't function without it).
The DPI was being enforced by the client to be 96 and I unchecked that and tried as well. But the issue appears when I just run 'nxagent :50" without any args. I expect it should throw open an empty window with a logo, but instead it comes out with that dreadful message.
I am handy with debugging and code. But my time is very limited because our company is running against some hard deadlines in 1.5 weeks... Working during weekends sucks...:(

So, here is why SecurityLookupIDByType() fails. Basically, looks like the Hash() in NXresource.c is returning an index for "id" which is referencing 0x0.
Anybody got any clues? What does XCSECURITY have to do with default font? What kind of madness is this?

Is there a quick way to build nx-libs without XCSECURITY? I am curious about the #else case (i.e. the code that's not using the XCSECURITY).
Does anybody have any ideas what about my setup is upsetting this?

We once had several crashes in nxagent font code and as a quick fix it helped to remove these fonts (on RHEL6):
Apr 29 15:27:45 Erased: xorg-x11-fonts-cyrillic Apr 29 15:28:26 Erased: xorg-x11-fonts-ethiopic
I have not found time to debug this further but it seemed like some fonts are not "clean" and result in corrupted structures inside nx. I'd say this is a bug in the old Xorg code nxagent is derived from. As I am currently backporting some fixes I might be worth trying a version with my fixes as soon as I am finished.

Sorry, I don't know.
I'd be interested in the output of xset q on your proxy side.

Uli,
Removing those fonts did not help. It still throws the same error.

It shows ~/.fonts in there. Having that folder present or not, does not make any difference. I think I am reaching the end of the rope here. I have run out of ideas. Unless and until someone here with the knowledge of how XCSECURITY stuff works, can lend a hand and suggest a workaround.

I finally decoded this issue. I can't believe it. The reason why its not able to load the default font and default cursor was that language specific fonts were missing from the /usr/share/fonts/misc folder. Those are missing because I have '-nls' in my global USE flags.
I had to spin up an Ubuntu 14.04 VM to figure this out...:) This is a packaging bug. nx package on Gentoo should force the 'nls' USE flag on media-fonts/font-misc-misc because without that nxagent is completely broken. I wonder how Xorg and Xvnc are fine without those! May be there is legacy code in nxagent which needs removal...:)
Thanks for all the help everyone! It was a pleasure dealing with you all. I hope the x2go community flourishes more and more everyday! -devsk

Please can you be more precise? Where do you set the -nls flag and how
can we get this fixed upstream in nx-libs?

He's talking about the Gentoo-specific USE flag feature, which lets you disable or enable features.
No, we cannot do anything about this.
However, there is another "bug report" pending for OpenSuSE, reproducing this issue. (-> "x2go on openSUSE")
This might be a related packaging issue, so it would be very interesting to know what missing file exactly caused this issue.

Yes, I am talking about Gentoo specific packaging issue. I have filed
https://bugs.gentoo.org/show_bug.cgi?id=559370
to track it down. As I mentioned, the specific files being talked about are the font files in /usr/share/fonts/misc (/usr/share/fonts/X11/misc on Ubuntu) which are character encodings specific e.g. 9x15-ISO8859-*.pcf.gz. nxagent can not load a fixed size font '9x15' without the presence of these files. It looks like these are abandoned by modern X code because both Xorg and Xvnc work fine without these files.

Thanks for explaining the above. However, I think that we should get
this issue also solved upstream as most systems work on UTF-8 basis
and the more local encodings are rather historical than
current-state-of-the-art.
Let's leave this bug open and address it for 3.6.x of nx-libs instead
of dealing with it as a Gentoo specific bug.

This issue will be fixed in nx-libs 3.5.99.4. The fix is to support
libXfont's built-in fonts as final fallback.
