Well, first of all, QMessageBox hasn't got a member 'message' - that's
KMsgBox, so I guess this is a type in QApplication. QMessageBox has
warning, information and critical - besides being able to constructed
beforehand and then exec_looped.

If I try     

  QMessageBox.critical(self, 'Note', 'Left as an exercise for the user.')
  QMessageBox.warning(self, 'Note', 'Left as an exercise for the user.')
  QMessageBox.information(self, 'Note', 'Left as an exercise for the user.')

everything works fine.  So, let's look at your errors:

You need to give a parent in QMessageBox, I think.

You give ThisApp - I don't know where it's coming from, but when you
show the msgbox from the main windows (QMainWindow), it's enough to
pass self.

Again, no parent.

Well, lots of luck with the rest of your app!
