#    Fix a crash when reparenting an item in QGraphicsView.
#    
#    Before calling addItem we need to invalidate the depth otherwise if
#    someone call anything relating to sorting when itemChange is called
#    (because of the scene change for instance) then qt_closestItemFirst
#    for example can crash because of an invalid state.
#    
#    Task-number:QTBUG-6932
