--- Comment #2 from Stefan Dösinger stefandoesinger@gmx.at 2009-11-06 15:53:17 --- Can you post a backtrace of the crash? I guess we're not checking a NULL pointer somewhere, or wrongly assume that certain extensions or GPU features are available, and thus run into a NULL pointer dereference because some object is not created.
