      Description

      Deleting a view that uses importScene and then deleting the importScene after that crashes when clearing materials. It happens because clearing materials marks model dirty, and dirty handling accesses sceneManager->dirtySpatialNodeList, which presumably is garbage at this point.

      This causes crash in QDS during qmlpuppet shutdown. It can probably be worked around there by not deleting the views at shutdown, though.

      See attached example.
