Summary0002610: MLT 0.7.8-2 causes Kdenlive to fail rendering (cannot use 2-pass rendering)
DescriptionWhen attempting to render any Kdenlive project on my Arch Linux install, the rendering process will crash at 99%, or 49% if using 2-pass rendering. The error log (see attachment) will show ffmpeg errors with H.264 encoding, swscaler warning that the data is not aligned and with some audio encoders, a warning that audio cannot be encoded.

Whilst the video is not corrupted, 2-pass encoding can never complete.

Kdenlive 0.8.2 and MLT 0.7.6 with the same version of ffmpeg worked fine without any errors or issues. Downgrading MLT 0.7.8 to 0.7.6 with Kdenlive 0.9 causes the same issue.
Steps To Reproducea) Install MLT, Kdenlive and ffmpeg packages and run;
b) Create a project and click the render option;
c) Select any encoding video and audio format and click render to file;
d) At 99% or 49% using 2-pass rendering, program will crash.
Additional InformationPackages installed are all stable versions from the Arch extra and community repositories:

MLT: 0.7.8-2
Kdenlive: 0.9
FFMPEG: 20120509-1
