GTK2.TreeView()->set_model() does not work as expected

Pike v7.8 release 700 on Ubuntu 14.04

int main (int argc, array(string) argv) {
    GTK2.setup_gtk();
    GTK2.Window window = GTK2.Window(GTK2.WINDOW_TOPLEVEL);
    window->set_title("TreeView Example");
    window->set_default_size(500,200);
    GTK2.ListStore store = GTK2.ListStore(({"string"}));
    GTK2.TreeView view = GTK2.TreeView(store);
    GTK2.TreeIter iter = store->append();
    store->set_row(iter, ({"flob"}));
    GTK2.CellRenderer renderer = GTK2.CellRendererText();
    GTK2.TreeViewColumn column = GTK2.TreeViewColumn("Name", renderer, "text", 0);
    view->append_column(column);
    window->add(view);
    window->signal_connect("destroy", lambda(){ exit(0); });
    window->show_all();
    return -1;
}

works as expected, but by changing to do a view->set_model() instead af passing the model to the constructor does not work. How should it be done?

int main (int argc, array(string) argv) {
    GTK2.setup_gtk();
    GTK2.Window window = GTK2.Window(GTK2.WINDOW_TOPLEVEL);
    window->set_title("TreeView Example");
    window->set_default_size(500,200);
    GTK2.ListStore store = GTK2.ListStore(({"string"}));
    GTK2.TreeView view = GTK2.TreeView();
    view->set_model(store);
    GTK2.TreeIter iter = store->append();
    store->set_row(iter, ({"flob"}));
    GTK2.CellRenderer renderer = GTK2.CellRendererText();
    GTK2.TreeViewColumn column = GTK2.TreeViewColumn("Name", renderer, "text", 0);
    view->append_column(column);
    window->add(view);
    window->signal_connect("destroy", lambda(){ exit(0); });
    window->show_all();
    return -1;
}
