Node table access must be by alias

After setting up i18n, I can't add custom box to dashboard anymore. I am getting next error:
user warning: Unknown column 'n.language' in 'where clause' query: SELECT nid, title FROM node WHERE (n.language ='uk' OR n.language ='' OR n.language IS NULL) AND ( type = 'feed' )ORDER BY title in /var/www/html/profiles/managingnews/modules/custom/mn_boxes/boxes/mn_boxes_feed.inc on line 17.

It seems that i18n uses SQL rewriting that expects for node table to be accessed by n alias. In most parts of managing news everything is OK. But mn_boxes_feed.inc and mn_boxes_feed.inc do not use an alias.

The problem can be easily fixed by altering SQL in this files introducing N alias as in all other places.
