Thank you for the report. I believe this issue to be fixed in youtube-dl 2015.03.24. See our FAQ if you need help updating.

@phihag

Basically the fix: f5e2efb results to a new Error.

I don't have time to check it but i think that the error occurs because you are trying to decode the options two times. One at the f5e2efb#diff-09f445e8685f0e866d7ff74c9481feecR800 and one at the https://github.com/rg3/youtube-dl/blob/master/youtube_dl/__init__.py#L195
