Yes - I'd forgotten I'd already taken care of this. If you look at the 
implementation of QCanvasItem.setCanvas() in qcanvas.sip, ownership is 
transferred to C++ if the item is now allocated to a canvas and 
transferred back to Python if it is not now allocated to a canvas.

Obviously, once ownership is back with Python the C++ dtor will get 
called when the Python object is garbage collected.
