This code looks buggy: All GL functions including glGetError require a (GLX in this case) context to be bound (otherwise IIRC the OpenGL spec says behaviour is undefined). glGetError() isn't meaningful for GLX functions like glXCreateWindow() anyway.
I agree about the wrong use of glGetError (and try to fix it), but it should not segfault.
Did you read this ? https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/318043 Many points have already been discussed there. See #12 and #13. Thanks
