New crash information added by DrKonqi

plasma-desktop (4.11.2) on KDE Platform 4.11.2 using Qt 4.8.4

- What I was doing when the application crashed:
Was doing programming in DrRacket.  Typed in a non-ending factorial function, which never terminated.  The Hard Disk started thrashing, and after some time this happened.
