--- Comment #18 from Stanislav Brabec 2011-03-29 15:29:41 CEST ---
Attaching more detailed (but different) backtrace.
I have a suspicion that this lock happens when you don't lock your screen
explicitly and don't touch the keyboard during the whole period of time.
I made this backtrace in gdb, sent kill to it. Then I returned to X. I was very
suprised that gnome-screensaver is still here, and it is no more deadlocked.
Program received signal SIGINT, Interrupt.
