-- 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.

kcmshell4 () on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

Got Logitech M555b mouse.  It had been paired and trusted for ages. Now it has been shown as paired only. Tried to mark it as trusted -- imideatly got error, now reporting it. If you wonder why I use BT mouse, it's because I've got laptop and do not want to occupy USB ports. Also my BT keyboard also stopped working

Git commit 9c4dee7de9447e23ac8e11c293597f7321b6585a by Alex Fiestas.
Committed on 08/10/2011 at 00:43.
Pushed by afiestas into branch '1.1'.

Close editDetails dialog when any device is changed

This is not perfect since we are closing the dialgo when anything
happens, but this is better than a crash. Will improve this in future
releases.
