gnome-screensaver-dialog crashed with SIGSEGV in gdk_property_change()

[Daniel Winzen]

My Computer was heavy overloaded with work and gnome-screensaver crashed while dimming the screen and shutting it down. It was a dark screen, but monitor didn't shut down. Moving the mouse or pressing a key on the Keyboard didn't help I switched to another console with CTRL+ALT+F1 and opened top. After a while the music playing in the background turned back and logging in into unity worked again. Then this apport bug-report came up.

Happening in 13.10 too, it was suspending while updates were installing, and I got this error.
