        ** See bug #53123.

        * em-folder-tree-model.c (drop_folder): changed to take store and
        dest folder as arg, to handle the case of the parent folder being
        "" properly.
        (em_folder_tree_model_drag_data_received): special case dropping a
        folder, and don't allow dropping to "" for any other types.
