The following happened:

Command run:

youtube-dl http://new.livestream.com/internetsociety2/hopex2

Latest version, installed from pip minutes ago. youtube-dl failed to continue after this uncaught exception, breaking the download of the remainder of the channel. I can reproduce the problem reliably; it always breaks on this video.

It's working now for me, so I'm closing the issue. If you can reproduce the error with the last youtube-dl version, please comment here or open a new issue.
