I got error "user already exists" when trying to rename user. (from "Pengguna" to "Matthew Brian" on id.wikipedia). I assume the user "Matthew Brian" is not exist from the newuser creation log and from its user and user talk page (pages not exists).
http://id.wikipedia.org/wiki/Istimewa:Listusers?username=Matthew%20Brian shows that user (currently) exists. The new user log doesn't show account creations before the log itself was added. Look up names in Special:Listusers in the future.
