Description Andreas Cord-Landwehr 2014-10-14 18:32:24 UTC

When formating an unmounted but plugged-in USB device (I used gparted) most/all applications crash. 
Here a backtrace from plasma-shell that shows the important Solid parts:

----------
Application: plasmashell (plasmashell), signal: Aborted
