Comment 6 for bug 386136

Hello Benno, believe it would be best if you opened a new bug report for the bug you are having. It seems to be a different bug, and a seperate report will help developers find it.

In the meantime, try:

sudo dpkg --configure -a
sudo apt-get -f install gnome-power-manager
