Package: client Version: 4.0.3.0 Qt 4.8.6
When we run our PyQt application on our Debian Wheezy computer with an ssh -X connection it work fine But when we use X2Go to access the computer and we run our application we've got a segmentation fault at the first QDialog opening. (when we run QDialog.exec_). We recently update the X2Go version and before that update it was working fine. We found at least one post that describe the same problem in January 2014 on your bug report site : X2Go Bug report logs - #410 Segfault of _X11TransWritev in libNX_X11.so.6 with libQtGui
Like suggested in this report if we run a simple application to test an opening of a dialog box it work fine with X2Go
From your experience of this bugs is there any way to solve this problem ?

Please send us a little Python snippet that lets your PyQt application crash.
I am currently working on the NX code tree, so your timing for
submitting this bug is quite good, right now.

Hello,
Thank you for your answer. I have made a simple python application (see the tar.gz attached) that reproduce the problem You will need PyQt4 to run it
The command is simple python gui.py
if it work it open a QDialog nearly empty If you reproduce the bug you will end with a segmentation fault with a very brief QDialog opening
Actually we have some doubts about our environment and we won't be surprised if you don't reproduce the bug with your PyQt4 But we want to close some of the paths of explanation of our bug and since it occurs only with X2Go we submit it to you
Regards

Sorry for getting back so late. We are currently working on the
nx-libs 3.6.x release and I have just tested your GUI example under
the development version of nx-libs.
The issue seems to be fixed there. I will merge this bug into #875
which is the tracking bug for the nx-libs 3.6.x upgrade in X2Go.

X2Go Bug report logs - #410 Segfault of _X11TransWritev in libNX_X11.so.6 with libQtGui
This is actually an issue in nxagent (aka x2goagent), not X2Go Client.
So reassigning.
