[Bug 780961] Re: Natty Xorg crashes on Thinkpad X201 (i915 driver) when using keyboard-based window management

 

I've been trying to avoid this, but as long as I had a crash today, I
decided to get more data.  I can consistently reproduce the crash by
starting X, starting 5 urxvt windows, then rapidly moving windows around
with H-arrow keys.  It takes maybe 15 seconds to trigger the bug in most
cases.

But first, I attached gdb.  I'll attach the full log momentarily, but
here is the traceback it found:
