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:

/usr/lib/python3.3/site-packages/PySide-1.2.1-py3.3.egg/PySide/libQtGui.so.4This 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]
- 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]
