 If you give an empty string for the `slug` part of the `rewrite` array in
 a `register_taxonomy` call, like:

 {{{
 'rewrite' => array(
      'slug' => ''
 )
 }}}

 ...you get some wacky permalink issues, even when you flush properly. In
 my case, I was seeing top-level pages (only) 404 while everything else
 worked. Removing this admittedly poor part of the code fixed it, but this
 should be checked for. The `register_post_type` function ensures this
 isn't empty, and this function should as well.
