      QBoxLayout::insertLayout() calls addChildLayout(), which may fail if the child layout already has other parent, but insertLayout() continues inserting the layout into its private item list nonetheless.

      Instead, insertLayout() should also fail if addChildLayout() fails. Alternatively, layout re-parenting should be implemented (see QTBUG-24420).
