My question why (look at the topic)?
Here is call stack:

Here is simple code that reproduce this problem:
#include <QApplication>
#include <QMainWindow>
#include <QWidget>
#include <QScopedPointer>
#include <QMenuBar>
#include <QMenu>
class MainWindowPrivate {
public:
MainWindowPrivate()
: m_widget( 0 )
{
}
QWidget * m_widget;
};
class MainWindow
: public QMainWindow
{
Q_OBJECT
private:
MainWindow( QWidget * parent = 0, Qt::WindowFlags f = 0 )
: QMainWindow( parent, f )
, d( new MainWindowPrivate )
{
init();
}
~MainWindow()
{
}
public:
static MainWindow & instance()
{
static MainWindow inst;
return inst;
}
private:
void init()
{
QMenu * fileMenu = menuBar()->addMenu( tr( "&File" ) );
fileMenu->addAction( QIcon(),
tr( "E&xit" ), qApp, SLOT( quit() ),
QKeySequence( tr( "Ctrl+Q" ) ) );
d->m_widget = new QWidget( this );
setCentralWidget( d->m_widget );
}
private:
Q_DISABLE_COPY( MainWindow )
QScopedPointer< MainWindowPrivate > d;
};
int main( int argc, char ** argv )
{
QApplication app( argc, argv );
MainWindow::instance().show();
return app.exec();
}
#include "main.moc"
