This generally happens because the Context.set_current is called before the real (platform specific) context has been initialised. Poking through the code I can only presume that we end up with an instance of BaseXlibContext instead of any of its subclasses.
stodge: Could you confirm the types of w1.context and w2.context from the multiple_windows.py example for your setup? Take a copy of the file and add 'print type(w1.context), type(w2.context)' before 'pyglet.app.run()'

Tried that but it doesn't help. The crash occurs "inside" the import:
from pyglet.gl import *
So my print statements are never reached.

I got the same on Fedora 12 with NVIDIA card and nouveau driver (for now it lacks 3D support). Try proprietary driver.

Sorry - forgot to mention that this was the proprietary NVIDIA driver.
