Are you writing your own TreeModel (using GenericTreeModel) or using
something like TreeStore?

I think you really should be using TreeIters rather than paths to
manage this mapping, since they directly map to rows in the model,
rather than positions in the treeview which may or may not match rows
in the model.

TreeStore TreeIters (and GenericTreeModel TreeIters if you're careful)
are also preserved across operations like sorting the Treeview, which
allows you to more flexibility in the future.

Since you can trivially go from either path format to the correct
TreeIter using get_iter(path), this also removes any need to worry
about the path format.
