What I was doing when the application crashed:
I do not know the exact reason of the crash, but I can list what it was I was doing when it crashed. I had just removed a pen drive, plugged in my ethernet cable, closed the SVN diff window from kdeSVN. Only other programme I had up and running besides kdeSVN was Quassel.
