Hi list,
after upgrading to the latest Debian packages, I can no longer run KDE applications in rootless mode - neither with NX nor with X2Go.
Steps to reproduce:
- Run Terminal as single application (not in a full-blown desktop - everything works fine there)
- Type: kdialog --yesno "Test"
- Session will crash
Affected system is Debian Squeeze (upgraded from Lenny).

Please fix this issue - it was what drove me from NX to X2Go, as the FreeNX guys couldn't figure out what caused the crash, and back then, X2Go worked just fine for me. Now it seems you've "crossported" the bug to X2Go. :-(
I have been in contact with Mike Gabriel regarding this issue, he suggests debugging the issue by stepping through the patches one by one. However, he won't get around to doing that in the next two weeks, and the last time I touched C code was 10 years ago and not much more than "hello world" stuff, so it's unlikely that I'll be able to find the reason myself. Anyone willing and able to assist?
What Mike suggested (paraphrased and translated for your convenience):
Clone nx-libs.git
git clone git://code.x2go.org/nx-libs.git cd nx-libs debuild -uc -us # 20min compiler run cd .. dpkg -i *.deb # Start testing... That will provide the current version of nx-libs. The directory debian/patches contains a file "series", which contains a list of the patches, commenting out a patch in this file will keep it from getting compiled in. Only one patch should be commented out for each compiler run, the relevant patches are the ones matching "1XX_*.patch".
Kind regards, Stefan

Stefan has been compiling NX between 0am and 4am in the morning until
he identified FreeNX patch
109_nxagent_locale-utf8-compound-text.full.patch
to cause the reported crashes.
Will take a look ASAP (probably tonight).

Just for the records. I have fixed the patch and am currently
preparing a bugfix release.

Dear Mike (and also Alex & Reinhard, as I'm not sure how large your part in this is/was, and I don't want to see you go uncredited if you were involved):
THANK YOU THANKY YOU THANK YOU!
This bug has been a royal pain in the *ahem* for months and was a large part (the others being NX4 going closed-source, and the inferior sound support) of what drove me away from NX (where nobody seemed to be willing/able to fix it) to X2Go.
Glad to see its presence in the X2Go code was very limited in time.
Kind Regards, Stefan
