consider these two lines 1) $output->setRobotPolicy( 'noindex,nofollow' ); 2) $this->setHeaders(); The first line is unnecessary because in the function setHeaders of SpecialPage . The "noindex, nofollow" policy is already set.
Fixed in https://gerrit.wikimedia.org/r/3678 ; will be backported to 1.19 later.
Thanks for the patch.
