Package: gnome-power-manager
Followup-For: Bug #510268
I can trigger the bug by removing my laptop's power cable. This basically
causes g-p-m to go into some kind of loop where it no longer responds to
external events (such as suspend button or brightness keys).
Here's the output of running g-p-m with --verbose, and a backtrace obtained
after it started to spin:
