Today I tried to gather some more information on bug #157579 and downloaded the video (http://media.revver.com/qt;sharer=0/159405.mov) that causes that crash. First of all: According to console debugging output, it seems that the video itself is somewhat corrupted / not properly recorded.

There are several ways to interact with the video that all lead to different behaviours:

- Case1: If I do a right click on the video and select Open with -> dragonplayer, dragonplayer crashes right at the beginning with backtrace A.

- Case2: If I play the video via "preview" embedded in konqueror and double click on it (make it fullscreen), dragon crashes as described in bug #157579.

- Case3: If I play the video via "preview" embedded in konqueror and wait until 0:14, it crashes with a corrupt backtrace. Note that if I play the video directly from the site, I only get some rendering artifacts at 0:14, but dragon does not crash. (However, when I close konqueror, it then crashes with a corrupted backtrace)

Backtrace A:
Application: Dragon Player (dragon), signal SIGABRT
Using host libthread_db library "/lib/libthread_db.so.1".
