cutting out part of a clip on the timeline track works incorrectly

[kornelix]

If part of a clip on the timeline track is cut out of the middle, the following part of the clip which was left on the timeline receives a few seconds of video from the part that was cut out. The audio for this part is also out of sync for a few seconds. Apparently the audio cut-out worked correctly but the video did not. I started over again and the problem repeated. In the same session, cutting part of a clip off the trailing end seemed to work OK. This was done with Ubuntu 12.10.

I could not get OpenShot to work at all on Ubuntu 13.04. The preview window was solid green, always. The app seemed to work otherwise, but of course working blind is useless.

The clip cutting problem was with ogg files from RecordMyDesktop. I changed to mp4 files from Kazam and the cutting problem went away. The green window with Ubuntu 13.04 is still there. OpenShot works fine with Ubuntu 12.04.
