Interesting... I never encountered this crash myself, but no, it is not a driver issue, this time, but likely a use after free...
If you compile the viewer yourself, replace the code for LLSpatialGroup::isHUDGroup() lines 146-150 of linden/indra/newview/llspatialpartition.cpp with:
(i.e. with an added "!isDead() && " test).
