listtree.py crash

[Issac]

ActiveState Python 2.1.1 and 2.2 both reject the listtree.py tkinter demo
(from the Python 2.2 source distro) :

$ python listtree.py listtree.py
Traceback (most recent call last):
  File "listtree.py", line 37, in ?
    main()
  File "listtree.py", line 33, in main
    list = listtree(f, app)
  File "listtree.py", line 11, in listtree
    listnodes(list, app, '.', 0)
  File "listtree.py", line 15, in listnodes
    klass = list.send(app, 'winfo', 'class', widget)
  File "c:\Python21\lib\lib-tk\Tkinter.py", line 582, in send
    return self.tk.call(('send', interp, cmd) + args)
TclError: invalid command name "send"

Does anyone know how to fix this?
