[OS X]: switching off icons in the "system tray" menu

[RJVB]

On OS X, Qt 4.8.6 appears not to respect the IconVisibleInMenu QAction setting for members of a "System Tray" menu.

This is easily shown with the systray example: change Window::createActions to

@
void Window::createActions()
{
minimizeAction = new QAction(tr("Mi&nimize"), this);
minimizeAction->setIconVisibleInMenu(false);
minimizeAction->setIcon(QIcon(":/images/bad.svg"));
qDebug() << "createActions" << minimizeAction << "icon=" << minimizeAction->icon() << "visible=" << minimizeAction->isIconVisibleInMenu();
connect(minimizeAction, SIGNAL(triggered()), this, SLOT(hide()));
// ...
}
@

and the console output will read

@
createActions QAction(0x115355cd0) icon= QVariant(QIcon, ) visible= false
@

but the minimise menu item will still have an icon.

Is this a known issue in Qt4, with a known workaround? Where in the Qt4 code could I look to fix this, if a patch doesn't exist already?

Also, when playing with the Qt5 systray example, I noticed that this 5.3 does respect the icon visibility when adding an action, but I can't seem to get the visibility to change dynamically (while changing the icon image works just fine)?
