I am getting an internalError when running a query that joins two subselects. The query looks like this:

SELECT data_table.title AS name
FROM
  ( 
    SELECT id, title
    FROM
    [citrius-altrius-fortius:analyze.topic_735_1354233600], [citrius-altrius-fortius:analyze.topic_735_1354320000]
  ) AS  data_table
  INNER JOIN
  ( 
    SELECT id FROM
    [citrius-altrius-fortius:analyze.topic_735_1354233600], [citrius-altrius-fortius:analyze.topic_735_1354320000]
    WHERE
    UPPER(title) CONTAINS ("BUDGET")
  ) AS filter_table
ON data_table.id == filter_table.id

this is the reply I get:

}

title and id are plain string columns (non-repeating). Both tables are fairly small in size (adding limit 1000 on the right side of the join does not change anything). When however, I alter the query to use just one table:

SELECT data_table.title AS name
FROM
  ( 
    SELECT id, title
    FROM
    [citrius-altrius-fortius:analyze.topic_735_1354233600]
  ) AS  data_table
  INNER JOIN
  ( 
    SELECT id FROM
    [citrius-altrius-fortius:analyze.topic_735_1354233600]
    WHERE
    UPPER(title) CONTAINS ("BUDGET") LIMIT 1000
  ) AS filter_table
ON data_table.id == filter_table.id

it works every time.
What would be the proper way of joining two subselects where they (subselects) are selecting from multiple tables?
