Your problem is in this line:
profile = UserProfile.objects.get_or_create(user=user)

Look closely at the documentation for the get_or_create method -
http://docs.djangoproject.com/en/dev/ref/models/querysets/#get-or-create-kwargs
You'll see it returns *two* arguments: the object, and a boolean to
show whether or not the object was newly created. Because you have
only given one name on the left-hand side of the assignment, Python
packs the two values into a tuple, which explains your error message.

Instead, use two variables:
profile, created = UserProfile.objects.get_or_create(user=user)
and all should be fine.

Could you please post more details.
a) Error is in forms.py or views.py or models.py ?

b) Can you figure out which lines are giving the error ?

You could use http://dpaste.com/ to paste the error details and send
us the link. that would save long email with error messages.
