ambigous query - warning message

Hi clemens,

thanks for working on this!

Have installed the module but getting following message on a new book page i composed:

* user warning: Column 'nid' in where clause is ambiguous query: SELECT uid FROM node LEFT JOIN i18n_node i18n ON n.nid = i18n.nid WHERE (i18n.language ='en' OR i18n.language ='' OR i18n.language IS NULL) AND ( nid=6) in /....database.mysql.inc on line 172.
* user warning: Column 'nid' in field list is ambiguous query: SELECT uid, nid, visibility, note FROM annotations LEFT JOIN i18n_node i18n ON n.nid = i18n.nid WHERE (i18n.language ='en' OR i18n.language ='' OR i18n.language IS NULL) AND ( nid = 6 AND 1=1) in .../database.mysql.inc on line 172.

The annotation doesn't show up either.

Cheers!
