This is 100% reproducable with my own laptop (f21 with upower-0.99.2)
Maybe there is something missing in the port to upower-0.99.x.
Sorry, i can't check this, i don't have a linux installed with older upower version on my notebook.
Here is my own stacktrace created with gdb.

I quess this report is also related to the problem.
https://bugzilla.redhat.com/show_bug.cgi?id=1195898
But i can't reproduce it because my wireless usb mouse isn't show in mate-power-statistics.
But everytime if the statistic tab is selected and i switched back to AC adapter on the left panel, mate-power-statistics crashed.

Seems it is upower related, see https://bugzilla.redhat.com/show_bug.cgi?id=1128390#c24
I will close this report when the patch is applied.
