Package: x2goagent
When starting a new x2go session, the startup scripts modify the LD_LIBRARY_PATH of all applications to include /usr/lib/nx/X11/Xrandr. This replaces the system libXrandr with the NX/X2go provided one. Unfortunately, this breaks the xrandr utility:
echo $LD_LIBRARY_PATH /usr/lib/nx/X11/Xrandr:/usr/lib/nx/X11/Xinerama:/usr/lib/nx/X11
xrandr xrandr: symbol lookup error: xrandr: undefined symbol: XRRGetScreenSizeRange zsh: exit 127 xrandr

this was done to work around a critical Ubuntu KDE bug in precise: https://bugs.launchpad.net/ubuntu/+source/libx11/+bug/985202
The path add-on for Xrandr is only done for KDE sessions. I will be
happy to revert that nasty hack, but before that, we need someone to
dig into KDE and (if I recall correctly) the patches applied to
libxfixes in Ubuntu 12.04 and beyond.
If you disable the LD_LIBRARY_PATH code for Xrandr (x2goruncommand),
then you will find regularly kwin crashes on KDE in precise+.
Greets, Mike

In that case I'm happy to confirm that your "workaround" does not fix anything in Kubuntu 12.10 nor when upgrading to raring.
If you disable the LD_LIBRARY_PATH code for Xrandr (x2goruncommand), then you will find regularly kwin crashes on KDE in precise+.
This also happens with this workaround.
What does help, however, is downgrading the libxfixes3 package to the version in oneiric.

I recently backport RANDR 1.5 extension to nx-X11's Xserver. Pull
request still open (but review is in process):
