[New-bugs-announce] [issue7914] IntVar() - AttributeError: 'NoneType' object has no attribute 'tk'

[Nick]

New submission from Nick <nick.allgood at gmail.com>:

I tried to run the attached code and it seems IntVar() dies in the Tkinter module. After discussion with several other coworkers they seem to agree this may be a bug in Tkinter. If you need more info feel free to let me know and I can help with further testing.

OS: Windows XP 32-bit SP2
Python: Python 3.1.1

Error:

Traceback (most recent call last):
  File "H:/code/python/hfprog_sounds/intvar-POC.py", line 3, in <module>
    num_good = IntVar()
  File "C:\Python31\lib\tkinter\__init__.py", line 265, in __init__
    Variable.__init__(self, master, value, name)
  File "C:\Python31\lib\tkinter\__init__.py", line 174, in __init__
    self._tk = master.tk
