When calling emit, you don't specify the signature. So in
LineEditCompleter.text_changed, you should call
self.emit(QtCore.SIGNAL("signalTextChanged"),names,prefix)
In addition, when using old-style signals, you don't need to explicitly
define the signal using QtCore.Signal, Because when you call QObject.emit
(or here, self.emit), it creates the signal dynamically.
Hope that helps!
