Hi Brice,
I finally managed to get the output from gdb (having installed
libgl1-mesa-dri-dbg as suggested - sorry for such a long delay.
Many times the crash when running in gdb would freeze my system -
sometimes restarting X would work, other times having to just use the
power button).
This time i got lucky (i don't understand why the symptoms aren't
exactly the same each time) and i copied the output to the attached file.
Regards
Alex
P.S. Should i log the incomplete drawing of glut shapes as a separate bug?

Blender crashes before even getting started (segmentation fault).
Can you catch a backtrace in gdb? Assuming the problem is in
libgl1-mesa-dri as Michel said, you might want to install
libgl1-mesa-dri-dbg, and enter 'bt full' in gdb once the crash occurred.
Thanks,
Brice
