No, no.  make_list() by itself is fine.  It sets its local iter in every 
iteration through the call to gtk_list_store_append().
The problem is that the global treedata.iter doesn't get set by the call 
to make_list().
If it /had/ been a call-by-reference parameter, then it would have been 
set to point to the last item in the model (which is perhaps also not what 
Rupert wanted but at least /something/ would happen).

1) Not necessary at all before calling make_list().
2) might be nice anyway -- but after calling make_list or perhaps inside 
the callback function.
But actually, the real question is: why keep a global iterator around in 
the first place?
