After running svn up to HEAD on my local MediaWiki, I got the following error notice plastered on top of the page (local file system path info replaced by {{$wgServerPath}}): User::$mEditCount in {{$wgServerPath}}\MediaWiki\includes\User.php on line 1596 This only happens during new account creation, and the error fades away afterwards. The error line, according to svn blame, was introduced in r19945, so it isn't live on Wikimedia yet.
Verified error, stops for me with r19960, marking resolved.
Cannot reproduce it anymore after r19660, marking verified fixed.
