unexplained behavior of tkMessageBox.as kyesno (2)

[Peter Kleiweg]

Here is a minimal example that produces the strange results:
#### begin code ####

#!/usr/bin/env python

from Tkinter import *
import tkFileDialog
import tkMessageBox

def openFile():
r = tkFileDialog.as kopenfilename(f iletypes=(("som e","*.ini"), ("all","*")) )
print 'openFile():', type(r), r

def askYesNo():
r = tkMessageBox._s how('yes/no', "Do or don't?", 'question', 'yesno')
print 'askYesNo():', type(r), r

root = Tk()
top = Menu(root)
root.config(men u=top)
mFile = Menu(top)
mFile.add_comma nd(label='Open. ..', command=openFil e)
mFile.add_comma nd(label='YesNo ', command=askYesN o)
mFile.add_comma nd(label='Quit' , command=root.qu it)
top.add_cascade (label='File', menu=mFile, underline=0)

root.mainloop()

#### end code ####

In the code above, I unpacked the original function
tkMessageBox.as kyesno(), which looks like this:
def askyesno(title= None, message=None, **options):
"Ask a question; return true if the answer is yes"
s = _show(title, message, QUESTION, YESNO, **options)
return s == YES
A session on a machine that goes fine:
askYesNo(): <type 'str'> yes
askYesNo(): <type 'str'> no
openFile(): <type 'str'> # selected 'cancel'
openFile(): <type 'str'> /home/peter/leven/L04/pyL04/Project.ini
askYesNo(): <type 'str'> yes
askYesNo(): <type 'str'> no

And here on another machine were things don't go as they should:
askYesNo(): <type 'str'> yes
askYesNo(): <type 'str'> no
openFile(): <type 'unicode'> # selected 'cancel'
openFile(): <type 'str'> /users3/kleiweg/pyL04/Project.ini
askYesNo(): <type 'bool'> True # causes problems, because True != 'yes'
askYesNo(): <type 'str'> no

Both are Linux machines running Python 2.3.4
The machine with problems has tcl/tk 8.4
The other machine has tcl/tk 8.3

Is this a bug I should report? Is it a bug in Python, or in tk?
