I did observe the problem when using the -U
option on Windows 2000. Seems like some infinite
recursion in cp1250.py -- see below.
I did not try it with earlier versions of Python.
Can this be reproduced on your computer?
Thanks for your time and experience,
pepr
P.S. Thanks, Martin, for the hint.

On Windows machine
C:\>python -U
'import site' failed; use -v for traceback

See the 'import site' failure. I do use the sitecustomize.py
(C:\Python24\Lib\site-packages\sitecustomize.py). It contains
-------------------------------------
import sys
sys.setdefaultencoding('cp1250')
-------------------------------------
I did remove the sitecustomize.pyc before the command.
When trying the python -U -v 2>xxx.log, I get the
following (shortened):
