With GtkTreeStore I think you do have to just copy the data.
You might file an enhancement request on http://bugzilla.gnome.org
about it.

If it's an efficiency concern, you can always write your own model, 
it shouldn't be difficult. Or alternatively, it's pretty easy to make
the tree store contain a single column with a pointer to a struct in
each row - see the "stock browser" demo in gtk-demo for example. Then
a copy will have essentially zero cost.
