It sounds like you need to put decorators before the slots that are
invoked when an action is triggered:

    def on_action_About_triggered(self):
        QtGui.QMessageBox.about(self, self.tr('About Application'),
                                self.tr('My Application does something\n'
            'This software comes without warranty, liability or support!'))

This is because there are effectively two forms of the triggered() signal:
one with a boolean parameter and one without. You need to specify which one
of these you want to receive.
