#25838: Viewing single posts of CPT 'author' result in 404 after upgrade

 Everything works fine in a clean install of 3.6.1 with this in
 functions.php:
 {{{
 add_action( 'init', 'create_custom_post_types' );
 function create_custom_post_types() {
     $args = array(
       'public' => true,
       'label'  => 'Authors'
     );
     register_post_type( 'author', $args );
 }
 }}}
 But after upgrading to 3.7.1 you can no longer go to a single page without
 getting a 404 error. This happens with or without permalinks enabled.

 Someone else has had the same problem here:

 This has affected 2 of my large live sites so hope it can be fixed soon.
 Thanks!
