Comment (by chamois_blanc):

 Here is a diff of a possible fix:

 {{{#!php
 <?php
         // Comment out this code
         // if ( ! empty( $t->rewrite['hierarchical'] ) ) {
         //  $q[ $t->query_var ] = wp_basename( $q[ $t->query_var ] );
         // }

         $term = $q[ $t->query_var ];

         // BEGIN - Add this code
         if ( ! empty( $t->rewrite['hierarchical'] ) ) {
           if ( is_array( $term ) ) {
             foreach ( $term as $k => $v ) {
               $term[$k] = wp_basename( $v );
             }
           } else {
             $term = wp_basename( $term );
           }
         }
         // END
 }}}
