EXPLAIN plugin doesn't work with a custom review/history tables names

Hi
I've a strange problem and don't know if I have to tune the explain plugin or there is some hidden bug somewhere. The problem is that if I use the default **global_query_review** and **global_query_review_history** the EXPLAIN plugin works without a hitch. But if I change for something custom like **mysql_05_query_review_history**, it doesn't work anymore. I just want to save all the slow query log data from several servers to the same DB and, at the same time, use different datasources in Anemometer for every source server. Am I doing something wrong or is it a bug?
