Make QObjects hashable

Hi, as suggested in the IRC of #Pyside, I have a problem with a code (which I use actually in PyQt, and works fine): http://pastebin.com/cScM9y33 The error is: self.pages[clientsModuleItem] = ClientsModule(self)TypeError: unhashable type: 'PySide.QtGui.QListWidgetItem'. I need the QListWidgetItem as key to referente the value (which is a widget class) since I use in a method like this: http://pastebin.com/WBuQ7fTR which is triggered by the signal.
