Operating System: Linux 2.6.31-19-generic i686

What I was doing when the application crashed:
No idea if what I was doing is related to the crash. I opened up a file with gvim and started highlighting text to copy and the crash occured. I had various other windows open like firefox, okular, konqueror, and eclipse.
