1. Module:Sandbox history splitted through delete & undelete. 2. Merged full history of Module:Sandbox to Module:Pagebanner through Special:Mergehistory. 3. Module:Sandbox fail. Full undeletion doesn't help.
The error message is: PHP fatal error in /srv/mediawiki/php-1.24wmf20/extensions/GeoCrumbs/GeoCrumbs.class.php line 126: Call to a member function getProperty() on a non-object getParserCache() can return null, but the code doesn't handle this situation, assuming it will never return null.
