$ youtube-dl -U
youtube-dl is up-to-date (2017.02.01)

Looks like a yt-dl issue. Did you try submitting an issue on https://yt-dl.org/bug, as suggested?

[rain0r]

My fault. I was confused because I was pretty sure I had the most recent youtube-dl version. The error was that there's a separate youtube-dl installation in my virtualenv that wasn't up to date.

Tricky error. Thanks for investigating!
