Note that my testing involved adding ‘DISTINCT’ to the query string in wp-includesuser.php (function WP_User_Query, subfunction query)
While this is not much of a solution, this testing ‘solved’ the issue […]
First of all, great plugin. Thank you!!
I have the same problem with both BP Labs and s2member enabled.
My testing indicates that this is related to WP bug #17582: http://core.trac.wordpress.org/ticket/17582
