Here's the debug log. Thanks a lot.

Failed to extract signature:

Be sure to call youtube-dl with the --verbose flag and include its complete output

If this is the indeed the complete output, then something is seriously wrong. It should start along the lines of [debug] System config: []. It also looks like you are running YSD instead of youtube-dl (see our FAQ about these issues). If that's the case, file the bug on YSD.

I'm closing this issue now since there is not enough information to solve it. If there is a command invoking youtube-dl that shows this behavior (hint: We need at least the video ID), please comment and we'll reopen it. Thanks!

@haquangvu, This issue disappeared when I upgraded from 2014.11.09 to 2014.11.13.2. I'm pretty sure that commit 894dd86 fixed it.
