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.

I guess the issue is the devkit-power-daemon crashes -- but looking at the backtrace it looks like a DeviceKit (rather than DeviceKit-power) bug. Are you running rawhide or F11? If F11, does it still happen in the GUdev world of rawhide?
Created attachment 28520 [details] [review] backtrace from the daemon backtrace from the daemon -- and it looks like DeviceKit itself might have gone pop, not just DeviceKit-power. (hint: all the devicekit-power functions and files start with 'dkp')
this was with rawhide (In reply to comment #2) > (hint: all the devicekit-power functions and files start with 'dkp') yeah, the trace from gnome-session and gnome-power-manager involved: #3 0x0062e801 in dkp_device_removed_cb (proxy=can't compute CFA for this frame ) at dkp-client.c:463 I didn't notice that any of the devkit daemons themselves were crashing too
