Bug description:
  Binary package hint: python2.6

  i was working on a python program that uses the pigment library (same
  one as elisa uses). I added a line that loaded another picture using
  gdk pixbuf (my program already loads several other images into pixbufs
  but after I added this one it crashes). the stack contains python
  stuff, pigment stuff, opengl stuff and intel driver stuff (this
  machine has an integrated intel G45 chipset).

  I was able to reduce my program down to a minimal testcase. Steps to repro the bug:
  1. run intel G45 (probably worsk on GM45 and other intel chipsets as well)
  2. run "python main.py"

  If you're in UXA mode you will get a SEGV in python2.6
  if you're in EXA mode you will get an xserver SEGV
