    app: ignore gimp_container_view_{select,activate,context}_item() ...
    
    ... while the container is frozen
    
    In GimpContainerView, do nothing in response to a
    gimp_container_view_{select,activate,context}_item() call while the
    view's container is frozen.  While the container is frozen the view
    is empty, and these functions can segfault.
