Description of problem:
If my xml recipe contains duplicate cc fields:

    <notify>
        <cc>mganisin</cc>
        <cc>mganisin</cc>
    </notify>

attempt to submit fails with error:

Exception: <Fault 1: 'sqlalchemy.exceptions.IntegrityError:(IntegrityError) (1062, "Duplicate entry \'120607-mganisin\' for key 1") u\'INSERT INTO job_cc (job_id, email_address) VALUES (%s, %s)\' [120607L, \'mganisin\']'>

Fault doesn't seem to be acceptable in this case. It is really simple to recover from this state.
