[Zope-dev] RESPONSE eaten while rendering a ZPT/maybe Python 2.3 issue

[Andreas Jung]

Hi,

while working with a Plone 2.0b3 site under Zope 2.7/Python 2.3.2 I 
encountered the
following error when I am trying to render a ZPT:

Error on the console:

AttributeError: RESPONSE (Also, an error occurred while attempting to 
render the standard error message.)

At the moment I have no idea where is error comes from (maybe a Python 2.3 
issue?!). At least
very strange.....
