QGraphicsScene core dump?

Could someone please tell me what is wrong with this piece of code? I'm using Qt 4.5.3 on Unix/X11

Code:

---

#include <QGraphicsView>    
#include <QGraphicsScene>    
 
int main(int argc, char *argv[])
{
    QGraphicsScene s;
    s.addText("hello");
 
    QGraphicsView v(&s);
    v.show();
 
    return 0;
}

---

It gives me a core dump right after I declare a QGraphicsScene with the following backtrace.

Well, I guess I have to have a parent window and an application ... Sorry my first post was dump :P

Code:

---

#include <QtGui>
 
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QMainWindow window;
 
    QGraphicsScene scene(&window);
    QGraphicsItem* item = scene.addText("hello");
 
    QGraphicsView view(&window);
    view.setScene(&scene);
 
    window.show();
    return app.exec();
}

You don't need the parent window. You need the application object though.
