Hi Bob,Here is an working connection that I use in one of my plugins:

self.point=gui.QgsMapToolEmitPoint(self.canvas)QObject.connect(self.point, SIGNAL("canvasClicked(const QgsPoint &,Qt::MouseButton)"), self.export)

Pay attention to "canvasClicked(const QgsPoint &,Qt::MouseButton)" it has to be exactly like that otherwise you will get no signal.
Regards,
Pablo.
