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

 

Using the debug packages you provided in #3, I get a different
traceback.  It's consistent across crashes, except for a few values.

Program received signal SIGUSR1, User defined signal 1.
