Bug 315253

Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.5
Qt Version: 4.8.4
Operating System: Linux 3.7.6-201.fc18.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- 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
Using host libthread_db library "/lib64/libthread_db.so.1".
