The next improvement you should try is to remove the iter field from the 
struct, remove the gtk_tree_model_get_iter_first() call before the call to 
make_list() and put a gtk_tree_model_get_iter_first() call into your 
callback function (probably as the first line of code after the 
declarations of the local variables).

Iterators are usually just used as a special kind of loop variables -- you 
don't make loop variables global just so you can use the same loop 
variable in another loop inside a completely unrelated function.  Or so 
that you can initialize a local loop variable to whatever value was left 
in the global loop variable from the last executed loop somewhere else.

Just get rid of it.

use gtk_tree_model_iter_next() inside your loop.  You can use it instead 
of normal loop variable: just call it until it returns FALSE.
