Description Isaac 2016-03-08 01:47:02 UTC 
Created a video project with webm files recorded with SimpleScreenRecorder and then proceeded to render the result. I set the export to webm, leaving all of the default options.
After clicking render, the process ends immediately, leaving an empty video file as result.

Reproducible: Always

Steps to Reproduce:
1. Open test kdenlive file.
2. Select Render menu
3. Select Websites > WebM
4. Click Render

Actual Results:  
Render ends immediately, leaving video file without information. Opening in vlc, results in nothing (as if no file had been selected). Dragon Player does not load either.

Expected Results:  
Rendered video with set duration.

I see the same, also with openSUSE Leap 42.1 on x86_64.

Isaac, I can't reproduce using recent beta 16.07.90 and MLT 6.2.0+. This looks extremely like a distro/packaging issue. Can you please report downstream to your distro packagers? Thank you very much for your cooperation.
