Rails - Apr 2006 - has_many through generated SQL column names incorrect

I just saw a post on this a few days ago but I''ve been searching and 
can''t find it again.  I have a has_many, through relationship, but when
I try to :include the join table in a

Model.find(:all, :conditions => "join_table.column = something", 
:include => "join_table")

the generated sql contains this where "grant_ownerships" is the join 
table and "grants" is one of the tables it is joining.

...

 LEFT OUTER JOIN grant_ownerships grant_ownerships_grants ON 
grant_ownerships_grants.grant_id = grants.id


See how there are underscores where there should be periods?
Is there a fix for this?

Sorry for the repeat question.
