Improper form element for Wildcard

In cache_actions.rules.inc, cache_actions_action_clear_cache_cid_form() the wildcard element is defined as

  $form['settings']['wildcard'] = array(
    '#type' => 'checkbox',
    '#title' => t('Use wildcard'),
    '#options' => $cache_bins,
    '#default_value' => $settings['wildcard'],
  );

'#options' => $cache_bins, should not be present and causes an error when you try and submit the form. Removing that from the element removes the error.
