Download is always truncated at 89.8% for this one video

[ekevoo]

Applies to the following video: http://youtu.be/7F7JC9q7Lz8

If I visit on the site clicking the link above I can watch the full video.

If I use youtube-dl, the video is truncated at exactly 89.8% (every time); and trying to continue the download won't work.

Downloading anew:

When I was on Windows earlier today and opened #9013 the behaviour was exactly the same, but I didn't remember to make the -v output then.

Confirmed with -f 22. As a workaround, install ffmpeg or libav, delete the incomplete file and retry.

For this video and itag 22, youtube served broken files. There's nothing youtube-dl can do. Try other formats.
