Comment 1 for bug 98823

Interesting, I've just been hunting and haven't managed to find the equivalent error or where it might have come from yet.

What version of g-p-m did this occur with?

  dpkg -l | awk '/gnome-power-manager/{print $2,$3}'

Could you also attach the schema file that you have now (or possibly the original is that is still saved as 'gnome-power-manager.schemas~').
