BogDan Vatra 6d3f81b095 Fix DockWidget ...

DockWidget keeps a pointer to the initial inner widget which might change/delete.

Ex:
    QWidget *w = new QWidget;
    w->setWindowTitle("title");
    QDockWidget *dock = addDockForWidget(w);
//...
    dock->setWidget(0); // we want to set another widget
    delete w;
