the crash occurs in libGL, the openGL implementation installed on your system.
now Gem uses openGL to do pretty much everything (actually [pix_video]  
could do without openGL, but you still need it to make Gem do  
_anything_ for you)

in order to give you better advise, we need to know:
which gfx-card do you use?
which drivers?
which Gem version?
