If I list the last 30 users on enwiki: http://en.wikipedia.org/w/api.php?action=query&list=allusers&audir=descending&aulimit=30 it works fine. But if I limit it to just 12: http://en.wikipedia.org/w/api.php?action=query&list=allusers&audir=descending&aulimit=12 I get this error: <error code="auinvalidtitle" info="Bad title "�Zipfiddle""/> The first character in that username is U+FFFD, "replacement character". If everything worked correctly, this username should have been in the query-continue tag. It seems that's where the problem is, because showing the same username in the list works correctly.
All the users showing with the bad character are quite low user ids. I wonder if they were created before the character blacklist came in, meaning they were valid then, but not now.
