I have the same or a very similar problem. Whenever gnome-power-manager starts up, it displays the correct status, but then it just stays there and never updates (not in case of plug/unplug, neither in case of charging/discharging).
If I do a 'killall gnome-power-manager; gnome-power-manager' the status is updated (and stays there). To me this looks as if gnome-power-manager were hanging somewhere.
