Change Details

Affects Mediawiki version 1.25.2. To reproduce the error: - enable categorized recent changes: $wgAllowCategorizedRecentChanges = true; - goto Recent Changes special page: /Special:RecentChanges - add a category filter - click the "Go" button Result: Fatal error: Call to a member function numRows() on a non-object in /var/www/partner_mediawiki/includes/specialpage/ChangesListSpecialPage.php on line 345 Additional notes: When submitting a query without a category filter ChangesListSpecialPage->getRows() returns an object of type ResultWrapper. When submitting a query with a category filter ChangesListSpecialPage->getRows() returns an array (when an array is returned later code fails becase ResultWrapper is expected). Thanks!
