-- Information about the crash:
- What I was doing when the application crashed: This service crashes at random all the time. It proves to be a huge annoyance. Today it has crashed 5 times will just surfing the web. It crashes when nothing is going on and the computer is locked. If I fart it crashes. If I go to pee it crashes. It crashed once because I was thinking about lunch. This crashes more than an application created by a certain company in Redmond, WA. I thought Linux was stable?

The crash can be reproduced some of the time.
