hook_menu requires a non-null title

From this issue >> https://www.drupal.org/project/drupal/issues/3021824 it appears that hook_menu requires a non-null title or issues can occur on DB CRUD actions.

This module does not set a non-null title, i.e.

  $items['<nolink>'] = array(
    'page callback' => 'drupal_not_found',
    'access callback' => TRUE,
    'type' => MENU_CALLBACK,
  );

  $items['<separator>'] = array(
    'page callback' => 'drupal_not_found',
    'access callback' => TRUE,
    'type' => MENU_CALLBACK,
  );

I believe I have encountered this issue on a site using Special Menu Items and perhaps a patch is in order.
