-- Information about the crash:
I believe it has to do with phonon as it wouldn't give me useful return data until i installed the phonon debugging symbols

The crash can be reproduced every time.

 -- Backtrace:
Application: Dragon Player (dragon), signal: Segmentation fault
The current source language is "auto; currently asm".
