Re: [Paraview] issue with python/qt wrapping on ubuntu: Cannot create GLX context. Aborting.
This crash is apparently due to my attempt at off screen rendering.
Not sure if it's and os mesa problem on ubuntu or just a problem with
the way I was trying to do off screen rendering.

Hi,
I've got an issue running a python/QT/VTK app built from the paraview-3.14
master branch and using qt-4.8 on ubuntu 11.04. This has been working on
darwin as recently as a month ago and used to work on linux. The code
crashes with error:

vtkXOpenGLRenderWindow (0x4ff4460): Cannot create GLX context. Aborting.
When I insert the python debugger before the main bunch of Qt setup code and
single step through it, the code runs fine without error. If I let it
continue and/or remove the debugging statement entirely, it gives me the
crash. I've include the python code below. Any ideas on what is causing
this?
Thanks,
