Trigger module does not work at all for non-core modules.

The patch is simple, and easy.

Still seeing no access callback specified there in D7:

  foreach ($trigger_info as $module => $hooks) {
    $info = db_select('system')
      ->fields('system', array('info'))
      ->condition('name', $module)
      ->condition('status', 1)
      ->execute()
      ->fetchField();
    if ($info) {
      $info = unserialize($info);
      $nice_name = $info['name'];
      $items["admin/structure/trigger/$module"] = array(
        'title' => $nice_name,
        'page callback' => 'trigger_assign',
        'page arguments' => array($module),
        'access arguments' => array('administer actions'),
        'type' => MENU_LOCAL_TASK,
        'file' => 'trigger.admin.inc',
      );
    }
  }

Uhm, they just replaced the custom checking with a general user permission. Hah. I think in D6 the expectation was that the user access callback would be inherited. Committed.
