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:
ERROR: In /home/cekees/proteus/externalPackages/ParaView/VTK/Rendering/vtkXOpenGLRenderWindow.cxx, line 629 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?
