Reversing video doesn't work in OpenShot v1.4.3

[Gannin]

Ubuntu 12.10 64-bit, OpenShot v1.4.3

Short and sweet: Take a video, extract a clip from it, try to reverse the clip, and nothing.

I made a little video demonstrating this:

Same problem when I modify the speed, reverse or not, the clip is replaced by INVALID in a large black square. No such issue in version 1.4.2. I use Mageia Linux.

It works for me with my various file types. I would suggest following the FAQ here:

Maybe you have an old version of MLT that doesn't like your particular source files, you may need to transcode them to another format.

I created a new video file using OpenShot to make sure I'd have a video file that OpenShot / MLT was happy with. Then I tried the same thing... added the new video clip, took just a section of it, tried to reverse it, and got the same result, where it just showed a black square instead of the reversed video. I'm using MLT version 0.8.8. And as I said, the video file I used as a test was created using this library.

I am being effected by the same exact bug show in the original description in video. I am using Ubuntu 14.04 LTS.

Anything I try to reverse just goes to a black still image.

I see the same issue on Ubuntu 14.04: The reversed clip is just black. Updating MLT as described in the FAQ doesn't help.
