Tkinter: wm_protocol() error on RedHat Linux 6.0

[Matt Gushee]

Hello, all--

The other day I released a small Tkinter application which I developed 
on a Red Hat Linux 5.2 system with Python 1.5.2 (my own build). A Red
Hat 6.0 user has reported the following error:

 >  ./surfnotes.py
 > Traceback (innermost last):
 >   File "./surfnotes.py", line 56, in ?
 >     snapp = SurfNotes()
 >   File "./sngui.py", line 164, in __init__
 >     self.wm_protocol('WM_DELETE_WINDOW', self.quit)
 > AttributeError: wm_protocol

He has tkinter-1.5.1-10.i386.rpm.

Anyone have an idea what might cause this?
