Hello, i get a segmentation fault when i emit a signal, down here there are some snippet of code, maybe somebody can give me a hint.
Thanks

clientsocket.h
Qt Code: 
  1. #include <QTcpSocket>
  2. #include <QtGui>
  3. #include "callApplication.h"
  4.  
  5. class ClientSocket : public QTcpSocket
  6. {
  7.     Q_OBJECT
  8.  
  9. private slots:
  10.     void generateError();
  11.     void readClient();
  12.  
  13. private:
  14.     CallApplication *callApplication;
  15.  
  16. };

clientsocket.cpp
Qt Code: 
  1. ClientSocket::ClientSocket(QTextBrowser *textBrowser)
  2. {	
  3.     connect(this->callApplication, SIGNAL(error()), this, SLOT(generateError())); //<-- segmentation fault
  4.     connect(this, SIGNAL(readyRead()), this, SLOT(readClient()));
  5. }
  6.  
  7. ClientSocket::readClient(){
  8. 	//read something from client...
  9. 	callApplication = new CallApplication(this->textBrowserPark);
  10. }
