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

I had just finished building a DVD ISO file using Devede and selected Burn to burn the completed ISO to DVD.  The system was just finishing with installing the "daily" updates we get with Kubuntu 12.04, when the crash happened.

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