[Zope] ExtFile Productz seems to be incompatible with Zope 2.6.2

[Andreas Tille]

Hi,

I'm the Debian GNU/Linux maintainer of the ExtFile product.  I checked
whether this product works with Zope 2.6.2 but I failed.  After creating
a new ExtFile object I tried to view this object but I got the following
traceback:

Traceback (innermost last):
  Module ZPublisher.Publish, line 89, in publish
  Module ZPublisher.BaseRequest, line 341, in traverse
  Module ZPublisher.HTTPResponse, line 636, in debugError

  <P>An error was encountered while publishing this resource.

  Zope has encountered a problem publishing your object.<p>
The object at http://localhost:9673/Test/ExtFileTest/testimg has an empty or missing docstring. Objects must have a docstring to be published.

Unfortunately I have not enough knowledge of the internals and I hope for
some help from the community to fix this problem.

Kind regards

            Andreas.
