Let admin A block user account B for 24 hours (autoblock disabled, account creation blocked, if that matters). Let user B log in and try to edit a page. The URL is http://some.wikipedia.org/w/index.php?title=Some_page&action=edit User B gets the [[MediaWiki:Blockedtext]] message: Your user name or IP address has been blocked. The block was made by A. The reason given is ''some reason here''. Start of block: 13:43, 27 May 2008 Expiry of block: 13:43, 28 May 2008 Intended blockee: B You can contact A or another administrator to discuss the block. You cannot use the 'e-mail this user' feature unless a valid e-mail address is specified in your account preferences and you have not been blocked from using it. Your current IP address is 1.2.3.4, and the block ID is #567. Please include either or both of these in any queries. -- Everything looks fine. The problem is when User B tries to edit a specific page version: http://some.wikipedia.org/w/index.php?title=Some_page&action=edit&oldid=1690914 The MediaWiki:Blockedtext message is used but some of the message parameter values are not provided correctly: Your user name or IP address has been blocked. The block was made by A. The reason given is ''some reason here''.

Nice catch! Actually, nine notices are also shown about calling non-objects etc. I'll try to fix it.
I figured that when a special revision id is given in the edit page url, $user on line 1065 of Title.php will be an instance of StubUser, while when no rev id is given, it is an instance of User. I didn't have time to trace it back and figure where this change occurs; I thought I'd write it here so another dev can follow it.
Looks like someone has fixed this bug without marking it as FIXED.
