Bug#610371: another work-around

[Selim T. Erdogan]

I have the same issue, though my gnome-power-manager version is
different (3.0.2-3).

The work-around mentioned above doesn't work as is, because on
my system (sid with gnome 3) there is no such field under "actions"
in gconf-editor.  

Instead, I installed the "dconf-tools" package and ran dconf-editor.
Here I went under "org->gnome->settings-daemon->plugins->power"
and changed "lid-close-battery-action" from suspend to nothing.
