Please make sure GL.glGenLists is returning what you expect it to return
(namely an unsigned int). On some platforms I've seen PyOpenGL bindings not
returning the generated value but rather expecting to assign it to the
second parameter in a similar fashion than that of the C API.

Hope this helps!
