Call to undefined function drupal_get_path_alias()

Call to undefined function drupal_get_path_alias() in /.........../includes/common.inc on line 1330

try this:

// load common.inc if necessary and path.inc
if (!function_exists('drupal_goto')) {
   require_once './includes/common.inc';
   require_once './includes/path.inc';
}

this is a bug.
require_once './includes/path.inc';
