Comment 2 for bug 73819

I can reproduce it now very reliable by

1. run on ac power
2. close the laptop lid
3. pull out ac and run on battery
4. open the lid shortly after 3
5. crash xorg

once I saw a notification while in screensaver in the bottop right corner about some battery event for a very short time after 4.

Propably affected packages (and I don't know how to narrow them)
 - gnome-screensaver
 - gnome-power-manager
 - gnome notifications
 - xorg
