Have reported to the bugzilla but i think the error lies within upower. As stated before the fix seems to remedy the issue that the battery status isn't updated at all and the gnome power manager reports this correctly. However when battery reaches critical there is no reaction from the gnome-power-manager. Looking at the printout below i think this is due to the fact that the upower Daemon does not recognize that the computer runs on battery or that the battery is low. If someone that knows anything about the signalling could point out what upower is supposed to report to let gnome-power-manager react then i could try to debug it but the signalling between the processes feels like black art to me.
