Binary package hint: gnome-power-manager

If I start my laptop without the power cable inserted, it will freeze
once the gnome background picture comes up. The mouse does not respond
and neither will the keyboard. I can see that the time has also stopped.

If I start the laptop with the power cable it works fine, until I remove
the cable. Then it will also freeze and become totally unresponsive. The
only way (I have found) to get it back and working is a hard reboot.

I have not seen this problem on Ubuntu 9.10 but it is 100% reproducible
(for me at least) on Ubuntu 10.04.

Without knowing anything about g-p-m, it is as if the cable-remove event
causes the laptop to crash.
