Bug 334944

Application: plasma-desktop (4.11.8)
KDE Platform Version: 4.13.0
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic x86_64
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

I clicked on "Panel Options" in the task bar, then "Add widgets", and I searched for "Pager" widget 
so that I could switch quickly between different virtual desktops. By the way I didn't need to do 
this in previous Kubuntu releases. All I needed to do was to select the number of virtual desktops
I wanted at "System Settings" -> "Workspace Behaviour" -> "Virtual Desktops" and my deskbar 
"Pager" widget would adjust automatically to reflect my choice. In any case, when I clicked in the 
"Pager" widget and tried to drag it towards the desk bar the plasma desktop crashed.

- Unusual behavior I noticed:

The screen became black with the exception of a few konsole windows I had opened at the time.
A few seconds afterwards the desktop returned to normal and the bug report window popped up.

The crash can be reproduced every time.
