New crash information added by DrKonqi

plasma-desktop (0.3) on KDE Platform 4.4.90 (KDE 4.4.90 (KDE 4.5 RC1)) "release 2" using Qt 4.7.0

- What I was doing when the application crashed:
Starting 'KThesaurus' via the application launcher plasmoid

- Custom settings of the application:
Vanilla plasma config with no 3rd-party stuff (just wiped after a different crash).
