Bug#522899: gnome-screensaver: Fails to activate when on battery

[Samson Wong]

Package: gnome-screensaver
Version: 2.22.2-2
Severity: normal

Gnome screensaver fails to activate when on battery, works fine when on power. Instead of the chosen screensaver (e.g. popsquares) activating, 
it would simply blank screen (screen/blacklight is still on - just a blank screen). It would still ask for a password, if you had set that option though.

This occurs whether the screensaver occurs naturally or when you use gnome screensaver to lock scteen.

When this happens, gnome power manager events (e.g. autosuspend) also do not happen.

Gnome screensaver will work as normal, if after being on battery, I kill it and start it again.

I am currently using fluxbox, with gnome-screensaver (and gnome power manager, I only have those two installed) put into the startup file, 
so it would autostart on login. I don't know whether this issue occurs in a standard debian gnome environment, (which has other things installed) 
might be a relevant factor.
