In MediaWiki messages that display usernames, if the parameter input is numerical, the software assumes that it must be a user id. This breaks the message for users with purely numerical usernames. This bug came to light after [[User:7]] on the English Wikipedia blocked themselves for April Fools, but the blocking user was displayed as [[User:Joao]] (user id 7). See the following: https://en.wikipedia.org/wiki/MediaWiki_talk:Blockedtext#.241_variable_is_not_working https://en.wikipedia.org/wiki/File:Blocked_Media_Wiki_Parameter_Problem.png
Given <https://test.wikipedia.org/w/api.php?action=query&list=allusers&aufrom=Jimbo+Wales&aulimit=1> (<u userid="6295" name="Jimbo Wales" />), I created User:6295 on test.wikipedia.org (using an admin account, as a global blacklist rule prevents strictly numeric usernames...). I blocked the account with my main account (User:MZMcBride) and the post-block success screen, Special:Log/block, Special:BlockList, Special:RecentChanges, and the various log excerpts (at Special:Contributions, etc.) all look fine to me. Special:Watchlist isn't showing the block of User:6295, but I think that's because the user did not yet have a user page (or possibly because the user account name was numeric...). This is a separate issue that I'll investigate elsewhere. I made User:6295 an admin on test.wikipedia.org and self-blocked. When I visit <https://test.wikipedia.org/w/index.php?title=Main_Page&action=edit> while logged in as the self-blocked User:6295, I see: --- You do not have permission to edit this page, for the following reason: Your account or IP address has been blocked. The block was made by Jimbo Wales. The reason given is testing. Start of block: 04:06, 2 April 2013 Expiry of block: infinite Intended blockee: 6295 You can contact Jimbo Wales 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 68.33.116.129, and the block ID is #15060. Please include all above details in any queries you make. --- Marking this bug as _confirmed_ (new) accordingly. (Hah! An April Fools' prank exposes a legitimate user interface bug.) Where the block message reads "Jimbo Wales", it should read "6295". I'm not sure how many MediaWiki messages are affected.

Gerrit change #57436 should cover Title::getUserPermissionsErrors().

Should be fixed in 1.22wmf3. Please file separate reports for any similar issues that are not related to the "blockedtext" and "autoblockedtext" messages.
