The form is not valid; check the data you are submitting and the form
definition to see why. The invalid form object itself will specify why
it is invalid, see the docs:
https://docs.djangoproject.com/en/1.4/topics/forms/#using-a-form-in-a-view
https://docs.djangoproject.com/en/1.4/ref/forms/api/#using-forms-to-validate-data
