[Zope] Problem with Automatic Cataloging Example in ZopeBook

[Chris McDonough]

Hi Christian,

Thanks for the report... I'm going to ask you to do one more thing, sorry.
Can you file this as a bugreport in the Collector
(http://classic.zope.org:8080/Collector)?  I unfortunately don't have time
to test this right now, but if it goes in the Collector, it'll remind me to
do so when possible.

In the meantime... please hang tight, sorry.

- C
