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

Already had the wetter.com weather widget on the desktop panel
wanted to add it again (with a different location) so I went "add widgets" and selected the weather plasmoid.
i dragged the plasmoid on to the desktop panel
The desktop seemed to lock up for about 5 seconds, and crashed at the same time as I was hitting the "esc" key repeadetly.

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