Now, this same error happened with this small program when called with 
-reverse.


#include <QtGui>

int main(int argc, char *argv[])
{
        QApplication app(argc, argv);
        app.setFont(QFont("", 72, QFont::Bold));

        QHBoxWidget *hbox = new QHBoxWidget(0);

        QSpinBox *spinBox = new QSpinBox(hbox);

        QSlider *slider = new QSlider(Qt::Horizontal, hbox);

        QObject::connect(spinBox, SIGNAL(valueChanged(int)), slider, 
SLOT(setValue(int)));
        QObject::connect(slider, SIGNAL(valueChanged(int)), spinBox, 
SLOT(setValue(int)));

        app.setMainWidget(hbox);
        hbox->show();
        return app.exec();

}
