Yes, but...

..."g_list_remove_link()" returns the new start of the GList, without
the element, and the loop was doing

        while (if_list != NULL) {
                g_free(if_list->data);
                if_list = g_list_remove_link(if_list, if_list);
        }

which amounts to

	while (there's anything in the list) {
		g_free(the data for the first element in the loop);
		remove that element and set the list to what remains in
		    the list - *not* to the remaining element;
	}

so, unless either

	1) the documentation for "g_list_remove_link()" is incorrect;

	2) "Returns: the new start of the GList, without the element."
	   doesn't mean what it sounds to me as if it should mean;

	3) the implementation is buggy;

the loop *will* traverse all elements in the list, as it's not using the
prev or next links.
