http://meta.wikimedia.org/wiki/Special:UserRights/Tim_Starling@enwiki gives the error "There is no user by the name "Tim_Starling@enwiki". Check your spelling." but it should of course be the same as http://meta.wikimedia.org/w/index.php?title=Special%3AUserRights&user=Tim+Starling%40enwiki which returns no error.
Fixed in r54429
Regressions with remote users fixed in r57064
