The crash seems to happen on the call to pglXQueryVersion. I'll attach a possible patch to catch the crash and report that opengl is broken.

--- Comment #2 from Roderick Colenbrander thunderbird2k@gmx.net 2008-03-01 09:39:40 --- As of latest git opengl initialisation isn't done by default anymore. It is only done when the use of OpenGL or Direct3D is requested. Nevertheless the same code is used.
I have seen issues like this before and it are Mesa / driver issues. Adding an exception for this case is very ugly. A few lines higher a GLX context is created and apparently that passes, so when we reach this code GLX must be around.

--- Comment #3 from Louis Lenders xerox_xerox2000@yahoo.co.uk 2008-03-01 14:02:55 --- I ran into this crash annoyingly about 8000 times. I thought it was a bug with my drivers. After logging out and logging in again, the crash was gone again, to reappear again after about half an hour. Latest weeks this crash has changed into another crash. If you want I can attach it here.

--- Comment #4 from Dan Kegel dank@kegel.com 2008-03-01 15:17:28 --- I'm more interested in whether my patch makes wine happier in that situation. Can you apply it?
Sure, it may be ugly, but the driver bug is kind of disabling for us, and I'd rather detect it than get screwed by it.
