    Bug 792991 - Crash when undoing a paste while naming pasted layer
    
    When removing a GimpContainerTreeStore item, make sure that editing
    of corresponding tree-view rows is canceled first, by emitting a
    "row-changed" signal.  Otherwise, we can run into trouble when
    removing an item that is being edited.
