Well, I can imagine that.

Btw: such problems also occur, when Qt wants a QBrush, and you want to 
give it a color, e.g.:

    def paintEvent(self, e):
        p = QPainter(self)
        p.fillRect(self.rect(), QBrush(Qt.black))

Qt seems to be able to cast a QColor to a QBrush in this case..

Maybe these cases deserve a little chapter for their own in the docs 
and an item in the sip wishlist.
