cometd.py KeyError in initHandshake

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Start the default/example cometd.py server
2. Start the twisted-cometd-client.py
3. Watch it throw a KeyError-Exception

Expected output: Connecting to the server, subscribing to topics.

Observed output: KeyError being raised
  File ".../python2.5/site-packages/cometd.py", line 491, in initHandshake
   if message["id"] is not None:
  exceptions.KeyError: 'id'


With: cometd-twisted SVN Rev. 462, Python2.5, Ubuntu Linux Gutsy.

Could be fixed with checking message.has_key("id") before trying to access it.
Or the twisted-cometd-client.py is the culprit with not sending a "id" field.

Both should be fixed ;)
