Housekeeping do not remove outdated information from trends_uint table.
Is it a bug?

zabbix-1.6.7/src/zabbix_server/housekeeper/housekeeper.c
-------------------------------------------------
deleted += delete_history("history", item.itemid, item.history, now);
deleted += delete_history("history_uint", item.itemid, item.history, now);
deleted += delete_history("history_str", item.itemid, item.history, now);
deleted += delete_history("history_text", item.itemid, item.history, now);
deleted += delete_history("history_log", item.itemid, item.history, now);
deleted += delete_history("trends", item.itemid, item.trends, now);
-------------------------------------------------
I think if add this line can fix it.Is it right?
deleted += delete_history("trends_uint", item.itemid, item.trends, now);
