This query (copied from the docs, with the apfilterlanglinks=withlanglinks parameter added) returns 5 results but only 3 unique pages. It appears to be returning one result for each language link on each page. Although this is not "wrong," the repetition is not helpful and is a waste of bandwidth, since there is no additional information to differentiate one result from the other.
Fixed in r41693.
