Yuck.

So the problem is that you've got a reference in an image's caption, which is inside a reference; this is not allowed in wikitext (as you can see from the "Cite error: A <ref> tag is missing the closing </ref> (see the help page)." error), and is because the restriction on media items' captions doesn't inherit the restriction of the reference block.

We'll need to build a way for restrictions to be explicit and inheritable.
