exploring Mantissa/Axiom/Epsilon/etc..

We are looking at writing a new hosting system and are taking a look  
at various python frameworks. We really like the idea of Axiom and  
have played with it in the past. We don't have any experience with  
Nevow/Mantissa/etc thought.

We checked out the latest tagged releases of the framework from svn.  
Everything looks fine ... but when we run the following command...

(after creating a new project with axiomatic)
axiomatic -d interlix.axiom mantissa

We get this error:

Traceback (most recent call last):

     return self._cursor.execute(sql, args)
pysqlite2.dbapi2.IntegrityError: axiom_objects.type_id may not be NULL

We added some debug print statements to store.py and this is the SQL  
we believe is being called and the arguments being passed to it:

('INSERT INTO main.axiom_objects (type_id) VALUES (?)', [2])

I don't see anything wrong with that myself.

Any help getting us started would be appreciated.

Thanks
