Comment 19 for bug 441646

Right, but gnome-power-manager has absolutely nothing to do with you not being able to log in to GDM when your disk is full. This bug is against gnome-power-manager, although I'm unconvinced that even the original reporters issue has anything to do with gnome-power-manager. You should open a new bug rather than hijacking other peoples bugs when it isn't clear that you have the same issue, otherwise it just becomes a mess and incredibly difficult for anyone working on it to extract useful information from.
