--- Comment #3 from Ilia Mirkin <imirkin at alum.mit.edu> ---
You can try the patch below and see if it ever triggers. Make sure to build
with --enable-debug (otherwise you won't get the assert). You'll also probably
want --enable-texture-float (I'd check how your distro builds it and do the
same thing).

Of course note that if gnome-shell is hitting this... the assert will happen in
gnome-session and it will crash :) If you could run it in gdb and poke around
at things when it does crash that'd be useful.
