Full backtrace etc. in https://bugzilla.novell.com/show_bug.cgi?id=466806

In short, during glutCreateWindow() ->.. fbOpenWindow() ->
MakeContextCurrent() is called, which calls driBindContext() with NULL
draw and read pointers. The code looks like this should never happen,
because the draw and read pointers are created in glxcurrent.c

375         if (gc && gc->driContext) {
376             __GLXDRIdrawable *pdraw = FetchDRIDrawable(dpy, draw, gc, pre13);
377             __GLXDRIdrawable *pread = FetchDRIDrawable(dpy, read, gc, pre13);
378
379             bindReturnValue =
380                 (gc->driContext->bindContext) (gc->driContext, pdraw,

from (seemingly) valid draw and read contexts. Just FetchDRIDrawable()
returns NULL.

Now what would be the right way to fix this / the right way to determine
what is actually going wrong here?

Thanks

Matthias
