 There's a bug in the taxonomy edit pages (/wp-admin/edit-tags.php). If you
 try to add a term that already exists, the following errors are thrown and
 display in a red box at the top of the page:

 Warning: mysql_real_escape_string() expects parameter 1 to be string,
 array given in /home/xxx/wp-includes/wp-db.php  on line 772

 Warning: mysql_real_escape_string() expects parameter 1 to be string,
 array given in /home/xxx/wp-includes/wp-db.php on line 772

 Warning: Cannot modify header information - headers already sent by
 (output started at /home/xxx/wp-includes/wp-db.php:772) in
 /home/juwcoope/public_html/wp3/wp-includes/classes.php on line 1697

 I think the fix is to edit wp-includes\taxonomy.php on lines 1526/1527
 like so:

 {{{
 //elseif ( is_term($slug, $taxonomy) ) // Provided slug issue.
         if (is_term($slug, $taxonomy) )
                 return new WP_Error('term_slug_exists', __('A Term with
 the slug provided already exists.'));
 }}}
