Public bug reported:

Binary package hint: xorg

Since about revision 24271 of blender 2.5 (self-compiled with scons):
reproduce:
start blender
within seconds one of my two cores flatlines at 100% blender use

happens both on this notebook with xorg-edgers and on an extensa 5635Z
with stock karmic.

was able to reproduce one time out of three with LIBGL_ALWAYS_SOFTWARE=1
on the stock karmic system.
