Comment 46 for bug 520941

I don't think it comes from MLT, I had this bug with default 10.04 MLT (5.6 ?, and openshot 0.9 ?) and still with latest kdenlive-ppa release (7.0 ? and openshot 1.4 ?). Besides I couldn't find any kdenlive bug report related to this.
As several comments state it, this is REALLY frustrating, because you've got this wonderful-looking piece of software and you can't get anything worthwhile out of it because of such a stupid bug. I'm really eager to make a lot of videos, upload them to YouTube and write at the end "This was made with Openshot, the best video editor I've ever seen, and it's free software !", but just now there's that bug and I can't.

@Bounty : interesting. I'll test on 64 bit, I just bought a new computer.
