PySide / Qt菜单栏在替换后消失

Question

I'm trying to replace the current Menu bar of my application with a new one (for when the user switches language), but after applying the change the menubar is disappearing. The strange thing is that the changes show for a split second before disappearing.

Any ideas what is happening? The QMenu is pretty standard (File, Edit, View, etc.), and I'm just calling setMenuBar() on my main window.

def reset_menu(self):
    menu_bar = QtGui.QMenuBar()
    ##
    ## Code to add menus and actions to QMenuBar
    ##
    self.setMenuBar(menu_bar)

Internationalization in Qt-based apps does not require manual recreation of GUI objects. The right way to do it is described here http://pyqt.sourceforge.net/Docs/PyQt4/i18n.html
