KDE Platform Version: 4.5.1 (KDE 4.5.1)

-- Information about the crash:
- What I was doing when the application crashed:

Watching a DVD. It had been playing fine for approximately 40 minutes, then decided to close for no reason. I performed no interaction with the window at the time of the crash. I didn't even have the mouse or keyboard in my hands!

The crash can be reproduced some of the time.

-- Backtrace:
Application: Dragon Player (dragon), signal: Segmentation fault
