Yes, as Edzard says: setting the label of the widget with label() does not *copy* the string, it only retains a pointer to it... which in your case then drops out of scope and garbage ensues.
I think I'd go with the copy_label() approach myself (which *does* make an internal copy of the string), and just let the widget manage the label string internally thereafter...
