Unhandled ProtocolError while downloading subtitles

[jarun]

Noticed the following in the logs while downloading a subtitle:

>> No subtitles found for this video:
E08. XXXIV. Jack and the Swamp Monster.mkv
Traceback (most recent call last):

    response.msg,
xmlrpclib.ProtocolError: <ProtocolError for api.opensubtitles.org/xml-rpc: 503 Backend fetch failed>

I believe this is because of a OpenSubtitles backend failure which I have noticed now and then from the browser as well. Can it be handled more gracefully?

Hi, Sorry for the delay, this should now be fixed with latest commit (08aa0b2).

Unhandled exceptions like this one from xmlrpclib will just prompt a single CLI error message. I did not added the xmlrpclib.ProtocolError in the regular error handler because it's not the same exception in python 2 or 3, and kind of annoying to handle properly :(
