Bug 308198

Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.2 (Compiled from sources)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-31-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

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

Attempted to run EEplasmid widget too task bar. didnt work. Removed it then attempted to add the widget to the desktop then it crashed after I tried it on the desktop. It coudlnt find something to monitor that it was looking for so I believe the widget crashed. Attempting to put it on the desktop didnt make KDE happy hehe.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
