Package: xserver-xorg-video-savage
Version: 1:2.1.2-5
Followup-For: Bug #423485
After installing the xserver-xorg-core-dbg, rebuilding
xserver-xorg-video-savage with "nostrip debug noopt",
adding NoTrapSignals to xorg.conf,
and running "ulimit -c unlimited" before restarting gdm,
I got this more complete backtrace.
