Description Jean-François Fortin Tam 2012-07-26 16:40:50 UTC 
Either run pitivi's:
python -m unittest discover tests/dogtail_scripts/ -v -p test_timeline.py

Or, in pitivi,
1. Insert sintel-stereo-1024.mp4 in a blank project timeline
2. Seek in the middle of the clip
3. Alternately press "s" (split) and the right arrow key

After a few splits, it will deadlock.
