-- Information about the crash:
- What I was doing when the application crashed:
I doubleclicked on a device in the list (Logitech M55b) to edit the details (set trusted = active).
While editing, suddenly the device disappeared from the list in the background.
At the same time, the Bluedevil KCM crashed.

-- Backtrace:
Application: KDE-Kontrollmodul (kcmshell4), signal: Segmentation fault
