Incompatibility with Localizer

Issue Summary

Hi everybody,

I am running into a problem that seems to be an incompatibility between Leech and Localizer. Whenever I click "leech data now" on my feed's page, I get, for every news item being leeched, a user warning:

user warning: Duplicate entry 'en-47' for key 2 query: localizernode_insert INSERT INTO localizernode (nid, pid, locale) VALUES (997, 47, 'en') in /var/www/apps/knowledge_framework/includes/database.mysql.inc on line 172.
user warning: Duplicate entry 'en-47' for key 2 query: localizernode_insert INSERT INTO localizernode (nid, pid, locale) VALUES (998, 47, 'en') in /var/www/apps/knowledge_framework/includes/database.mysql.inc on line 172.
user warning: Duplicate entry 'en-47' for key 2 query: localizernode_insert INSERT INTO localizernode (nid, pid, locale) VALUES (999, 47, 'en') in /var/www/apps/knowledge_framework/includes/database.mysql.inc on line 172.
[...]

It turns out that the node in question (node 47) is the feed's template, i.e., the one node of content type news article that it used to create news article nodes (using node_template). Does anybody have an idea how to solve this, or where the cause may lie?

Many thanks for any input,
Kaspar
