      If I close my window using an action with connection

      connect(ui->actionQuit, &QAction::triggered, qApp, &QApplication::quit);

      it will trigger a slot connected like this

      connect(ui->dockWidget, &QDockWidget::visibilityChanged, this, &MainWindow::dockToggled);

      but not like this

      connect(ui->dockWidget, SIGNAL(visibilityChanged(bool)), this, SLOT(dockToggled()));

      despite the fact they should do the same thing. This causes a crash if dockToggled() uses QMainWindow::saveState().
