Thanks Diez,
Removing, rebooting and installing the latest version solved the
problem. :)
Your google-foo is better than mine. Google had not turned that up for me.
Thanks again
Regards
Ian

Hi all,
I have hit a problem and I don't know enough about python to diagnose
things further. Trying to use couchDB from Python. This script:-
# coding=utf8
import couchdb
from couchdb.client import Server
server = Server()
dbName = 'python-tests'
try:
db = server.create(dbName)
except couchdb.PreconditionFailed:
del server[dbName]
db = server.create(dbName)
doc_id, doc_rev = db.save({'type': 'Person', 'name': 'John Doe'})
Gives this traceback:-
D:\work\C-U-B>python tes1.py
Traceback (most recent call last):

Why? I've tried adding u to the strings, and removing the # coding
line, and I still get the same error.
Sounds cargo-cultish. I suggest you read the python introduction on
unicode.
http://docs.python.org/howto/unicode.html
For your actual problem, I have difficulties seeing how it can happen
with the above data - frankly because there is nothing outside the
ascii-range of data, so there is no reason why anything could be wrong
encoded.
I came to the same conclusion.
But googling the error-message reveals that there seem to be totally
unrelated reasons for this:

Maybe using something like tcpmon or ethereal to capture the actual
HTTP-request helps to see where the issue comes from.
