Django request.POST contains <failed to parse>

I have a django form to get username, password. when the user sends the data, I see that in the message dictionary there is the following (traceback), Traceback (last last call):

Why does the dict post have "<smog parse>" and why is CONTENT_TYPE not? This does not allow me to go to the login page.

This is my form

   <form method="POST">{% csrf_token %}
       <tr>
     <td><label>Email Id</label></td>
     <td>{{form.username}}</td>
     <td><label>Password</label></td>
     <td>{{form.password}}</td>
   </tr>
    <input type="submit" name="btn_login" id="btn_login" class="btn_login" value="Login" /></td>

  </form>

Forms.py:

class loginForm(ModelForm):
    username = forms.CharField(max_length=50)
    password = forms.CharField(max_length=50, widget=forms.PasswordInput(attrs=  {"autocomplete":"off"}))

    class Meta:
        model = User

View:

def login(request):
 if request.method == "POST":
   log.inof(request)
 else:
  request.session.set_test_cookie()
  form = loginForm()
  return render_to_response('login.html', {'form':form},context_instance=RequestContext(request))

NOTE. I also found that all requests come only from mobile devices, especially Blackberry. Another user seems to have the same problem.
