Variable 'wgCirrusSearchCompletionGeoContextSettings' is not set.' in /srv/mediawiki/php-1.29.0-wmf.16/maintenance/getConfiguration.php:105

The global wgCirrusSearchCompletionGeoContextSettings is defined in wmf.15 but not in wmf.16. I'm not sure why the maintenance code is validating globals for 16 against those defined in 15? It doesn't make sense to me...
