New crash information added by DrKonqi

plasma-desktop (0.4) on KDE Platform 4.7.3 (4.7.3) using Qt 4.7.4

- What I was doing when the application crashed:
Attempting to set content plugins on firefox 7.0.1 - multiple attempts caused this crash to persist repeatedly

- Unusual behavior I noticed:
Machine slowed down to a crawl about 10 to 15 seconds prior to the crash
