Such errors usually happen when u pass a NULL to a gtk_list_* function that doesn't want a NULL
Do you know that (as of gtk2.0) GtkList is by twice obselete? use GtkCList ferchrissakes, or if you are writing for 2.0, GtkTreeView/GtkListStore :)

Course I don't know how to write for any of the above. Maybe GtkList is easier or something. And you do have a book on it. But it's gone way out of favor..
