Is Acidfree compatible with i18N? user warming: ambiguous query: SELECT

We are integrating a basic multi-language ca/es/en version. At the moment all is right but today installing Acidfree as photogallery appears this user warning:

Column: 'nid' in field list is ambiguous query: SELECT COUNT(nid) FROM ca_node n INNER JOIN ca_acidfree ON ca_acidfree.aid = n.nid INNER JOIN ca_acidfree_hierarchy ON child = aid LEFT JOIN ca_i18n_node i18n ON n.nid = i18n.nid WHERE (i18n.language ='ca' OR i18n.language ='' OR i18n.language IS NULL) AND class <> 'album' AND parent=7 AND CONCAT(LPAD(CONVERT(5555555555 + ca_acidfree.weight, CHAR), 10, '0'), LPAD(CONVERT(9999999999 - ca_acidfree.aid, CHAR), 10, '0')) < '55555555559999999991' in /home/ca/public_html/ca/includes/database.mysql.inc on line 120.

For this reason, we will be very grateful if anybody can confiorm the compatibility i18n with acidfree.
thanks in advance,
