get traceback while trying to see/use --list-subs.

Hi all,
I'm on Debian testing and use youtube-dl .

$ youtube-dl --version
2013.08.17

$ python --version
Python 2.7.5+

I got a traceback when trying to use the option --list-subs.

$ youtube-dl --list-subs "https://www.youtube.com/watch?v=dCCLhE4QDe8"

sub_lang = ",".join(list(sub_lang_list.keys()))

Looking forward to resolution. Please lemme know if I need to give some more info. or I have used the command in a wrong way or something.

What should happen is it should either say if there are subs., if there are no subs. then it should say something to the effect that there are no subs. Crashing this way is not good.

Thanks for reporting, we knew the problem (#1213) and the issue is fixed in newer versions of youtube-dl, run sudo youtube-dl -U to update.
