Bug 356081

Application: dragon (2.0)
KDE Platform Version: 4.14.8
Qt Version: 4.8.6
Operating System: Linux 3.19.0-33-generic x86_64
Distribution: Ubuntu 15.04

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

I opened a mp4 movie (over the network from a smb path). The Dragon player was unable to play the movie. After hitting the close button the Dragon player crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: Dragon Player (dragon), signal: Aborted
