Error In SQL Syntax

WP 3.42 on PHP 5.3

[05-Nov-2012 07:14:13] WordPress database error You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘)) AND (wp_usermeta.meta_key = ‘wp_47_capabilities’ ) ORDER BY user_login ASC LI’ at line 1 for query SELECT meta_value FROM wp_sitemeta WHERE meta_key = ‘translation_ops’ AND site_id = 1 made by WP_Users_List_Table->prepare_items, WP_User_Query->__construct, WP_User_Query->query
