Xorg log

Debian sid, with xserver-xorg-core 1.4.1 (git20080131-1), -intel 2.2.0.90-3, ThinkPad X60 with 945GM.

Sometimes, but not always, when I play a movie in Totem, X crashes.  This happens more frequently when the movie is embedded inside Epiphay, but that is probably not related.

So far all I have is this backtrace from xorg.log (full log attached).

Backtrace:
0: /usr/bin/X(xf86SigHandler+0x7e) [0x80c675e]

I'm installing -dbg packages now to get a better log when it next occurs.
