Upgrade to a more recent version of youtube-dl with youtube-dl -U, it was fixed in c91778f.
Thanks for the report.

1st thing I do is I use youtube-dl -U. I got this yesterday night. Above as pushed 21 days ago.

As seen in the debug version you are using an outdated version (2013.12.04), if you get the same error in more recent versions, please post the output you get and we will reopen the issue.

Same problem here with the latest version as for now.

@hakermania Your version is over a year old. Since we release nearly every day, I cannot fathom why you'd think of it as the latest. Running sudo youtube-dl -U once should be sufficient to update.

[hytromo]

You are absolutely right. I was almost sure that it wrote 2015 there and not 2014. My bad.
