title: KeyError in Django form kwargs
body: <pre><code>def user_info(request, template_name='social/retrieve_user_data.html', username=None):
      user = User.objects.get(username=username)
      if request.method == 'POST':
          form = UserInfoForm(request.POST, user)
          print(form.is_valid())
          if form.is_valid():
              form.save()
      else:
          print('not post')
          form = UserInfoForm(user)
  
  
      return render_to_response(template_name, RequestContext(request, {
          'form': form,
      }))
  
  
  class UserInfoForm(forms.Form):
  
  
      def __init__(self,*args,**kwargs):
          self.user = kwargs.pop('user')
          super(UserInfoForm,self).__init__(*args,**kwargs)
  </code></pre>
  
  <p>This is producing a KeyError with exception value u'user'. What is wrong here? In both cases, form is initialized with a valid value of user. Why am I getting a keyerror></p>
