Like @dstftw noted this Crunchyroll URL is geo-restricted - only people from allowed regions can check the issue. (I can't access that URL)

Looking at the line where error is thrown (1) it would appear that video_url var (extracted earlier in the same function) is None.

From what I can tell, what is throwing the error is actually a bug on crunchyroll's own website.

For @elitefroggy's two episodes:
http://www.crunchyroll.com/shin-sekai-yori-from-the-new-world/episode-6-escape-611581-- if you try to play the 360p ('SD') video it's busted in their own player but their site gives you the option to watch the higher qualities.

http://www.crunchyroll.com/shin-sekai-yori-from-the-new-world/episode-20-a-cold-and-sunlit-place-611609, if you try to play the 480p video it's broken on the site while 360p is just fine and dandy.

When crunchyroll.py hits these two errors is when it crashes and spits out the 'NoneType' error message (because technically being passed is an empty URL string). I'm not a coder so I wouldn't know how to make crunchyroll.py just ignore the dead link errors and just not let you download said dead format links.

Hope that helps.

Edit: To get a specific video format via web browser, you specify it as part of the URL, so example: http://www.crunchyroll.com/shin-sekai-yori-from-the-new-world/episode-6-escape-611581?p480=1 brings up the 480p video from elitefroggy's first problem link. if you use the same link with youtube-dl, it still tries to download all the media info for all the various formats and then tosses out the same 'NoneType' error.

Maybe change https://github.com/rg3/youtube-dl/blob/master/youtube_dl/extractor/crunchyroll.py#L342:

 if video_url is not None and '.fplive.net/' in video_url:

Works for me with my patched version.
