Which is equivalent to

lb.bind('<Leave>', "break")

But I checked and overriding the default behavior of Listbox does not 
work (tk.tk.call('bind', "Listbox", '<Leave>', "break")).

So I would subclass Listbox and do the bindings in the __init__:

class MyListbox(Listbox):
   def __init__(self, *args, **kwargs):
     Listbox.__init__(self, *args, **kwargs)
     self.bind('<Leave>', "break")
