[Twisted-web] exception in formless with a few nevow examples

This is my first post to the list and I'm quite a newcomer to twisted and
nevow, so forgive me if the issue is already known. The problem is with some
Nevow examples (e.g. formpost, userdb, db, customform, formbuilder - you can
see the problem at
following exception occurs when the samples are run:
exceptions.NameError: global name 'cf' is not defined
With the exception of userdb (which seems to give a slightly incorrect
traceback for the exception), the problem seems to originate at line 449 in
447 def formRenderer(ctx, data):
448 cf = ctx.locate(iformless.IConfigurableFactory)
449 return util.maybeDeferred(cf.locateConfigurable, ctx, configurableKey
I'm not sure whether my guess is correct, but I perhaps the local 'cf'
variable has been garbage-collected before the _runCallbacks routine in
twisted/internet/defer.py calls the _formRenderIt?
I'm not familiar enough with Python yet to check whether my assumption is
right or not, but I'm sure somebody on the list will be able to verify that
without any problem.
I'm using twisted 2.0.1, latest Nevow svn and python 2.4 on an Ubuntu/breezy
