[Zope] ZTopics not working right --Error Value: Vocabulary

[Chris McDonough]

From what I remember, the TextIndex code wants to acquire the catalog's
Vocabulary subobject.  If you created your catalog without a Vocabulary (I
think this is an option during the instantiation of a catalog), this can
occur.  This is arguably a bug.  The vocabulary object should probably not
be acquired.  Do you think you can submit this to the "Collector" at
Zope.org (http://classic.zope.org:8080/Collector)?
