[PyQt] Segfault when trying to use QtOpenGL

[Berthold Höllmann]

I just installed SIP 4.11.1 and PyQt x11 gpl 4.7.6 on SuSE Linux 11.2.
When I start qtdemo I get:

X Error: BadLength (poly request too large or internal Xlib length error) 16
  Extension:    136 (Uknown extension)
  Minor opcode: 17 (Unknown request)
  Resource id:  0x17
QGLContext::makeCurrent(): Cannot make invalid context current.
QGLContext::makeCurrent(): Cannot make invalid context current.
Unrecognised OpenGL version

The OpenGL samples do not work (empty widgets). Trying to debug the
problem I came across this segfault:

hoel at pchoel:~> python -c "from PyQt4 import QtOpenGL; QtOpenGL.QGLFormat.openGLVersionFlags()"
Speicherzugriffsfehler

How do find find out what OpenGL Version is supported? And why does the
simple script above segfault?

A: TOFU
