playing hokey-pokey with UPS USB interface crashes gnome-session
Submitted by Dan Winship @danw

Description
If you have a UPS with a USB interface, and you put the usb cable in, then take the usb cable out, then put the usb cable in (and you shake it all about), then remove it again, then everything linked to libdevkit-power-gobject (including, in particular, gnome-session, but also gnome-power-manager and gpk-update-icon) will crash.
(the CFA errors are rawhide gdb being broken)
