Wrong page argument

In the hook_menu(), there is a reference to the wrong page argument.

These code lines cause the page callback to get 'title' like argument, which I guess it is not the desired thing:

  $items['teleport/autocomplete/title/%menu_tail'] = array(
    'title' => t('Autocomplete title'),
    'page callback' => '_teleport_autocomplete_title',
    'page arguments' => array(2),
    'access arguments' => array('use teleport'),
    'type' => MENU_CALLBACK,
    );
