--- Comment #1 from Vittorio <zeccav at gmail.com> ---
I believe this situation comes from a NULL pointer in nouveau_dri2.c:246
"r = nouveau_bo_name_get(nouveau_pixmap_bo(pixmap), &front->name);"
because nouveau_pixmap_bo returns a NULL pointer and 
nouveau_bo_name_get dereferences it.
Should the caller update_front handle this one, 
or the called nouveau_bo_name_get?
This is from xf86-video-nouveau-1.0.9.
Many codes provoke this bug, as in /usr/lib64/mesa/teapot.
