I'm confused. I can't reproduce this error with release 1.00a4 on either
UNIX (FreeBSD) or Windows. It looks like the line that causes the
problem is on 534 in the original file, so I guess you have been
modifying this file?

As far as I know, we all tend to use the all-spaces style. This has the
advantage of looking exactly the same in all editors, and I think is the
way code in the main python distribution is being written. The more
popular unix editors like emacs and vim do the 4 spaces indentation
automagically. Anyways, it's all a matter of preference.

If you have been mixing spaces and tabs in the code that is going to
cause the indentation problems. You can do:

python -t <your_script>

to look for tab/space mixing problems. Python comes with
Tools/scripts/untabify.py, which can convert tabs and spaces, and you
can also do this in text editors, etc.

Hope this helps!
