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

Attempting to place world clock widget onto desktop. I seemed to have a problem with the LCD weather widget as well. I canceled it after waiting approx 30 seconds, so not quite sure on that one.

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