Code

function layout_provides_path($path) {
  if (empty($path)) {
    return FALSE;
  }

  $result = db_query('SELECT * FROM {menu_router} WHERE path = :path', array(':path' => $path));
  $return = NULL;

  // If any page callback exists at this path, allow it to trump custom layouts.
  foreach ($result as $router) {
    if ($router->page_callback == 'layout_page_callback') {
      $return = TRUE;
    }
    else {
      $return = FALSE;
      break;
    }
  }
  return $return;
