Description of problem:
Hi !

I was trying to build a sub file from scratches using a mp4 rip from youtube.

Opening and playing the video was ok, extracting the wave was fine too.

It crashed everytime I tried to create key frames from video, pretty early in the process too.

Thanx for attending to this.

subtitleeditor-0.40.0-4.fc19
