[Zope] Zope hanging: internal ZODB error?

Michel, I take back the assertion in my private email.

I've just determined that this glitch in my
CatalogAware Journal ZClass (using a custom catalog
as per http://www.zope.org/Members/AlexR/CatalogAware)
arises whenever a user edits an instance of this class.  

Users are using the standard Zope management interface 
but I have substituted the standard Properties View 
with an "Edit Journal" View.  This is a copy of the 
Journal_AddForm method (with default values culled from 
the now existing instance).

As per #4 in the above How-To, on submission this calls 
the following DTML method which puts my publicationCatalog 
in a strange state (requiring the update):

<html><body>

<dtml-call "propertysheets.Properties.manage_changeProperties(REQUEST)">
<dtml-call reindex_object>
<p>Changes saved.</p>

</body></html>

I desperately need to sort this out before users start
making changes.  I certainly can't do an update of
the catalog on every edit of an existing Journal
instance.

Any help is much appreciated.

Cheers,
Darran.
