Application: choqok (1.0)

Qt Version: 4.7.3
Operating System: FreeBSD 9.0-CURRENT i386
Distribution (Platform): FreeBSD Ports

-- Information about the crash:
Choqok was updating the twitter timeline.   Occasionally Choqok will hit this crash over and over as it tries to create preview for the same video.   Other times, simply restarting Choqok will avoid the crash.

Waiting a while until the particular 'tweet' is out of the timeline cache will work around the problem. 

As an aside it would be nice to be able to toggle video previews off/on in settings.

The crash can be reproduced some of the time.
