New crash information added by DrKonqi

plasma-desktop (0.4) on KDE Platform 4.8.2 (4.8.2) using Qt 4.8.1

- What I was doing when the application crashed:

Had various apps open and system was under heavy load, plasma crashed for no apparent reason though, I wasn't interacting with it at the time. Restarted OK but found a lot of blank entries in my systray which i had to hide.
