Ok, I've found my mistake and how to properly use the annotations. For
the records and if someone has the same interrogations, the proper
solution is to write:
> /* Returns: (transfer none):*/
> GtkTreeIter* gtk_list_store___iter__(GtkListStore *list)
> {
> GtkTreeIter *iter = g_malloc(sizeof(GtkTreeIter));
> return iter;

/* @iter: (out caller-allocates): */
void gtk_list_store___iter__(GtkListStore *list, GtkTreeIter *iter)
{
[...]
}
which will indeed create a Python routine like that:
iter = gtk.list_store.__iter__()
And the Python __iter__() routine on the iter itself
(http://docs.python.org/library/stdtypes.html) should be:
/* @out: (out caller-allocates): */
void gtk_tree_iter___iter__(GtkTreeIter *iter, GtkTreeIter *out)
{
*out = *iter;
}
Like that, there's no memory leak and the iteration interface in Python
works well (except for the StopIteration issue).
Damien.
