The problem is that you have auth.signature but are doing inserts without a
logged in user. As a result, the values of the created_by and modified_by
fields are None but are required to be id's from the db.auth_user table.
This should simply result in a failed validation rather than an exception,
but the IS_IN_DB validator breaks when None values are passed in for id or
integer fields (I would consider it a bug).
