[Bug 312017] [NEW] [Intrepid] X server crash (in libexa?), Intel 915GM, no compiz

[Andrew Bennetts]

Public bug reported:

Binary package hint: xserver-xorg-video-intel

X just crashed for the first time in a long time.  I didn't do anything
out of the ordinary; I was browsing the web with epiphany.  It seemed
that the crash was triggered by switching between tabs with Ctrl+PgDn
while viewing pages on www.cricinfo.com.  No OpenGL (from compiz or
anything else) or flash animations/videos were involved that I know of.

The screen was corrupted (mostly black, some vertical dotted lines, and
a static mouse cursor), and gdm was unable to fully restart X, leaving
me with a corrupted screen (when gdm gave up the there was no change to
the corruption or the position of the mouse cursor, but the mouse cursor
had changed from a pointer to a frozen "busy" wheel).  I had to hit
Ctrl+Alt+Delete to reboot to get a usable display back.

I'll attach the full Xorg.log, but for convenience here's the backtrace
from that log:
