gdb output

Unfortunately, the patch in bug #10809 doesn't fix this bug.
I'm attaching gdb output when trying to reproduce this bug. I was able to reproduce it after my second attempt.

Steps I did to reproduce it:
1. Disable compiz and enable compiz again.
2. Switch to VT1 and switch back to VT7.
3. Repeat steps 1 and 2 several times.

You can replace step 1 with playing some video file using xv, but sometimes you get a SIGABRT and end up with bug #12437.

After the last "step" in the output attached, you can see the gray blocks and the whole laptop hangs (no networking, sysrq, etc.).

I was using:
xserver-xorg-video-intel 2:2.1.1-0ubuntu5
xserver-xorg-core 2:1.3.0.0.dfsg-12ubuntu8
