I've been seeing this all over the internet and the mailing list for a
while but I haven't really seen a fix yet. I'm running Ubuntu Jaunty
and I have an AMD 9000 Radeon FireGL. I understand that Ubuntu Jaunty
and AMD chips are the biggest problems so I thought this might be
relevant. I get a segmentation fault after a call to window.Window()
and my backtrace is here.

Not sure how a call to glGetString() would cause this issue, but i'm
really really want to try pyglet, and i'm willing to try any sort of
work arounds, short of changing my video driver.
