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

[Jan Evert van Grootheest]

Binary package hint: gnome-power-manager

I unplugged my laptop and worked for a while. Then it crashed.
My guess is g-p-m was about to (or busy doing it) pop-up one of those warnings that I had only 10 minutes of estimated battery time left. I had just checked it before and it was at 11 minutes...

This happened two times (out of two times). So I guess it is pretty reproducible.
Any requests on how to debug this? Or which package I need to install to produce a useful backtrace (I'm a programmer, just with little knowledge of g-p-m).

Thanks.
