E-notice - implies error in civicrm.module / localisation

This looks pretty trivial $config is being used but isn't instantiated in civicrm_preprocess_page() - implies something might be broken? This is in the D6 version in 3.4 (which is also being used for trunk

$localisation = explode( '_', $config->lcMessages );

Assume we just need to add right above it.

require_once 'CRM/Core/Config.php';
$config = CRM_Core_Config::singleton();

Notice: Trying to get property of non-object in civicrm_preprocess_page() (line 927 of C:\webroot\d6\sites\wcan-t\modules\civicrm\drupal\civicrm.module).
