As mentioned above this works as far as it runs but doesn't show any tool tip.
But I think that by using 'self.applet' it registers the 
PyKDE4.plasma.PopupApplet instead of the 
applet_pypopupapplet.main.PyPopupApplet which is a subclass of Python 
PopupApplet.

I tried to implement toolTipAboutToShow to see if it was called but it wasn't. 
Instead was called:

  @pyqtSlot(name="toolTipAboutToShow")
  def toolTipAboutToShow(self):
    print "PyPopupApplet:toolTipAboutToShow"

From ~/.xsession-errors:
QMetaObject::invokeMethod: No such method SpellCheck::toolTipAboutToShow()
QMetaObject::invokeMethod: No such method SpellCheck::toolTipHidden()
QMetaObject::invokeMethod: No such method 
Plasma::PopupApplet::toolTipAboutToShow()
QMetaObject::invokeMethod: No such method Plasma::PopupApplet::toolTipHidden()

As you can see the SpellCheck  Applet toolTipAboutToShow is called but for the 
derived Python applet the Plasma::PopupApplet::toolTipAboutToShow is called.

I have no idea about the inner workings of the bindings (it's dark magic to 
me) but to me this indicates that that - well - something isn't working the 
way it's supposed to...

I'm cross posting again as I really don't know if I should file a bug report 
and if so against which package.
