Comment:

 The problem is that `wp_match_mime_types()` fails if
 `$wildcard_mime_types` contains regular expression special characters like
 "+".

 The attached patch uses the technique from WP_oEmbed: replace "*" with a
 non-special string, preg_quote(), replace the placeholder string with
 "[-._a-z0-9]*".
