Summary: Win32: subprocess.Popen() w/o "pipe" throws an exception

Initial Comment:

This is under Windows (XP).

I have a script which calls subprocess.Popen without
the "pipe=" argument, as so:

--
from subprocess import *
Popen("cmd.exe /c dir") 
--

If I run that with Python 2.5, it throws the following
exception:

Exception exceptions.AttributeError: "'NoneType' object
has no attribute 'append'" in <bound method
Popen.__del__ of <subprocess.Popen object at
0x00C04EB0>> ignored 

The same script run under Python 2.4(.2) does not throw
any exceptions.

Note that this happens with any call to
subprocess.Popen; what process you invoke seems irrelevant.
