Comment (by kontur):

 Even when passing in my augmented mimes again as $overwrites (which I
 shouldn't have to) in
 https://core.trac.wordpress.org/browser/tags/4.7.2/src/wp-
 includes/functions.php#L2326 finfo returns the type for my uploaded woff
 as ""application/octet-stream", which contradicts the mime received from
 the file extension which wp_check_filetype() correctly extracted, alas
 $ext and $type get set to false, which triggers the error message then.
