Thank you for your report!

However, processing it in order to get sufficient information for the
developers failed (it does not generate an useful symbolic stack trace). This
might be caused by some outdated packages which were installed on your system

I've been seeing this bug as well, but I'm on an x86_64 machine using the current Ubuntu Karmic nVidia drivers. Should I attach an xorg log here, or open a new bug given the difference in hardware ?
