export video file adds a few black frames at the end of video

[Teo]

When you export a video (File/Export video), a few black frames are systematically added at the end of the exported video.

Steps to reproduce:
- import a video file
- place it on the timeline
- cut a slice of it by using the razor tool or whatever it is called. So you end up with 3 clips on the timeline
- remove the first and last clip and keep only the center clip. This is to make 100% sure the footage doesn't have a black frame
- place the only remaining clip at the very beginning of the timeline
- export video

Result: the exported video has a few extra black frames at the end.

This is absolutely critical (not to mention annoying)

I don't experience this with any of my files. What format files are you using?

Input files are flv encoded with h264 and I'm exporting them as mov encoded with mjpeg

They include audio. Have you tested with audio? (just in case it's related)
