Description:
The way Special:Userrights is written causes it to stop reading username once it reaches a @ symbol, and then check for the -interwiki right. While this would work on a new installation, it lacks backwards compatibility for wikis that have users with an @ symbol in their username, before this was disallowed. The software thinks you are changing a user at another wiki, not a local user with @ in their name. While a user with the -interwiki right might be able to do username@whatever@wikiname [not tested], this is still an issue.
