[web2py] Object Row. Error in 2.0.8 not in 2.0.0

[Jose]

Hi all

In Version 2.0.0 (2012-06-04 18:49:33) dev works well

Model:

tb_studio = db.define_table('studio',
    Field('name', label=T('Name')),
    #...
    format='%(name)s',
    migrate=MIGRATE
)

tb_emails = db.define_table('emails',
    Field('studio', tb_studio, readable=False, writable=False, default=1),
    Field('email', label=T('Email')),
    migrate=MIGRATE
)

Controller

def bg_studio():
    row = db(tb_studio.id==1).select(cache=(cache.ram, 60)).first()
    email = row.emails.select().first()    

    return dict(row=row, email=email)


In Version 2.0.8 (2012-09-07 09:38:35) stable, error occurs:

File "/usr/home/jose/web2py/applications/dm/controllers/default.py" 
<http://127.0.0.1:8000/admin/default/edit/dm/controllers/default.py>, line 45, 
in bg_studio
    email = row.emails.select().first()
AttributeError: 'Row' object has no attribute 'emails'
