php 7.1 sadness. The fix is to change this:

  // Add local actions as the last item in the local tasks.
  if (!empty($variables['action_links'])) {
    $variables['tabs']['#primary'][] = array(
      '#theme' => 'menu_local_actions',
      '#menu_actions' => $variables['action_links'],
      '#attributes' => $dropdown_attributes,
    );
    $variables['action_links'] = FALSE;
  }

to:

  // Add local actions as the last item in the local tasks.
  if (!empty($variables['action_links'])) {
    if (empty($variables['tabs']['#primary'])) {
      $variables['tabs']['#primary'] = array();
    }
    $variables['tabs']['#primary'][] = array(
      '#theme' => 'menu_local_actions',
      '#menu_actions' => $variables['action_links'],
      '#attributes' => $dropdown_attributes,
    );
    $variables['action_links'] = FALSE;
  }
