Thanks for the stack trace (the complete one is here: http://launchpadlibrarian.net/28836332/Stacktrace.txt).
How repeatable is the crash? Are there steps you can do to recreate it? When you say "the screen turns black" - is it because of GPM screen blanking, screen saver, or this crash? Thanks! ** Description changed: Binary package hint: gnome-power-manager Using a laptop, the screen turns black for less than 1 second. It can happen several times a day.
