good question! I think iteration from a arbitrary row
is not an use case. Usually you catch ROW_EXPANDED
just to get some of the row values (i.e calling
model.getValue()). But the question is: is that a
problem for us? Can we assume the user is not going to
iterate, and thus leave model to null? In my opinion
this is a bad solution, because in that case we have a
set of TreeIter methods that sometimes work, sometimes
not! It is hard for the developer to figure out in
which situations it is valid or not, even if we
carefully document that. 

In my opinion, we should try to keep the same behavior
for all iterators, despite of where they come from.
Anyway, it is not hard to achieve, it is implemented
in my branch!

And note that other methods that need the model, such
as children(), are really useful in a ROW_EXPANDED
handler, so...

Cheers,
Vreixo
