gnome-power-manager crashed with SIGSEGV in fclose()

[Mathieu]

Binary package hint: gnome-power-manager

This bug happens everytime I start my computer. Right after logging in, a window appears which reads "system program problem detected" and lets me choose between two buttons: 1) Report 2) Close.
Until yesterday this bug didn't happen. Instead, a window opened to tell me an authentication certificate for empathy IM was unvalid and that I needed to accept it. This used to happen systematically upon logging in, disregarding the fact I kept checking the box saying "Remember this choice for future connections".
