Comment 2 for bug 822181

This problem still occurs under Oneric 11.10. When selecting the battery panel in g-p-s without the battery installed it will immediately crash. It will also crash when the battery is removed while the battery panel is being displayed.
Terminal output from running gnome-power-statistics directly with sudo:
