[PyQt] PyQt snapshot crash on Qt5.4 with bogus QGraphicsVideoItem instance

Removing the %ConvertToSubClassCode in qgraphicsvideoitem.sip did not
seem to help. I assume you mean in /usr/share/sip/PyQt5...
A reduced example failed to exhibit the same symptoms. This is a
snippet of a reduced example:
def addToGroup(self, item):
assert item in self.childItems()
In my app it prints:
DrawMorphHandleItem at scenePos PyQt5.QtCore.QPointF()
[<PyQt5.QtMultimediaWidgets.QGraphicsVideoItem object at 0xa9cf8b74>]
and the assertion fails. In other words, the Qt method setParentItem()
puts some garbage object in childItems.
The mro of the garbage object doesn't include the class of my 'item'
object, I'm not using QGraphicsVideoItem anywhere.
I will build the example more like my app and try again, but I don't
understand why the behaviour should depend on the class of 'item.'
