QWizardPage's icon margin is missing with AeroStyle if back button is disabled on last page

How to reproduce:

Use licensewizard example.

In main.cpp, disable back button on last page:

LicenseWizard wizard;
wizard.setOptions(QWizard::NoBackButtonOnLastPage);
wizard.show();
return app.exec();

In licensewizard.cpp, set AeroStyle and icon:

#ifndef Q_OS_MAC
//! [3] //! [4]
setWizardStyle(AeroStyle); // or do not set at all
setWindowIcon(QIcon(":/images/logo.png"));
#endif

Run the wizard till last page. Notice the missing icon margin on upper left corner.
