When using python apps with QT (either PyQT or PySide), any interaction with the resulting window (when connected from windows to linux) causes the program to crash. Partial stack trace:

This just happened with the Jan 4 update to nx-libs (et al).
For comparison, using a basic ssh connection with X-forwarding and starting an xterm session and running the same python programs succeeds.
sorry for responding soooo late...
Today, I have been in NX code for the whole day and I wonder, if I can do something for you to get the above issue fixed.
I tested the above with this python snippet:
""" #!/usr/bin/python
# simple.py
import sys from PyQt4 import QtGui
app = QtGui.QApplication(sys.argv)
widget = QtGui.QWidget() widget.resize(250, 150) widget.setWindowTitle('simple') widget.show()
sys.exit(app.exec_()) """
and I don't bump into any problems as described above.
Can you please:
- get latest x2goagent/nxagent/libnx-x11 from our nightly builds[1] 2. re-test the above
- if you get the same error, send me the python code that triggers the bug
Greets, Mike
PS: please wait for the current build of nx-libs to finish [2]

As I am on Archlinux, I need to apply patches from the debian/patches directory from the git pull. Besides the Pgn.cpp patch (for libpng), what other patches need to be applied to make the git behave like the nx-libs-3.5.0.xx-full.tar.gz releases? (for example to create a master Makefile).
nx-libs/debian/roll-tarball.sh is your friend...
But Clemens already helped out on IRC I just saw...

I went ahead and changed the PKGBUILD file (Archlinux's package building spec file) to include the symlinks as you pointed out (and as are contained as comments in the Makefile) and rebuilt the package. It works!! (pyQt, PySide, vlc all work now). That was the fix that was needed and will report this to the package maintainers.
Regarding your assumption, it is actually incorrect. I do not have Xinerama checked as an option in my session profile (it is unchecked) so that had no bearing on the issue rearing itself.
Thanks!!

Great that we could track this down...
