Sounds like a libGL problem.  if you upgraded to a newer dri snapshot
or messed with your X install, you may have an old version of libGL
floating around that some apps are using.  try:
ldd `which glxinfo`
and compare it with the results of:
ldd `which otherapp`
and see if they are linking to the same version of libGL.

Which other apps are giving you problems?
