I must be missing something here. I have tried (Python syntax) the following 
ways:

    self.arrow_down_icon = KIcon("arrow-down")
    self.collapse_button = Plasma.PushButton()
    self.collapse_button.setIcon(self.arrow_down_icon)

The Button shows no Icon.
Then to be a bit more explicit I tried:

    iconloader = KIconLoader()
    print "Path: " + str(iconloader.iconPath("arrow-down", iconloader.Small))
    # prints the correct path
    self.arrow_down_icon = QIcon(iconloader.iconPath("arrow-down", 
iconloader.Small))
    # prints false
    print "Failure? " + str(self.arrow_down_icon.isNull())
    self.collapse_button = Plasma.PushButton()
    self.collapse_button.setIcon(self.arrow_down_icon)

And the Button still shows no icon.

I'll probably be slapping my forehead when someone points out what I'm doing 
wrong :-)
