Исключение Null Pointer при вызове SetRegistrationListener

Question

После вызова sipmanger.open внутри расширяющегося потока класса. Я проверил, были ли какие-либо параметры пустыми, а они нет.

Любые идеи?

private void setlisten() throws SipException { 
    sipman.setRegistrationListener(sipprofile.getUriString(), new SipRegistrationListener() { 

     public void onRegistering(String localProfileUri) { 
      Message msg = Message.obtain(); 
      msg.what = 10; 
     } 

     public void onRegistrationDone(String localProfileUri, long expiryTime) { 
      Message msg = Message.obtain(); 
      msg.what = 93; 

      Log.d("register", "register done"); 
     } 

     public void onRegistrationFailed(String localProfileUri, int errorCode,String errorMessage) { 
     }  
    }); 
} 

Стек след в залежах:

Двойная проверка, что переменные sipman и sipprofile не являются null.
