permission declared in module doesn't match permission referenced by menu item

In menu_clone v 6.x-1.0-beta2, menu_clone.module on line 36 it reads:

     35 function menu_clone_perm() {
     36   return array('access menu clone');
     37 }

Then on line 49 it reads:

     42 function menu_clone_menu() {
     43   $items = array();
     44
     45   $items['admin/build/menu-customize/%menu_clone/clone'] = array(
     46     'title' => t('Clone menu'),
     47     'page callback' => 'drupal_get_form',
     48     'page arguments' => array('menu_clone_clone_form', 3),
     49     'access arguments' => array('access clone menu'),
     50     'type' => MENU_LOCAL_TASK,
     51     'file' => 'includes/menu_clone.admin.inc',
     52     'weight' => 20,
     53   );
     54
     55   return $items;
     56 }

Since these don't match - "access clone menu" vs "access menu clone" - only the admin user has access to clone menus. Please make them consistent - not sure which one you want to use.
