[Zope] more __len__ errors

[Chris McDonough]

Hmmm... Zope 2.1.6 has known catalog issues.  So does 2.2.X for that
matter, but at least some of them have been fixed (not to mention that
later versions of Zope log errors in cataloging and uncataloging
objects).  The Zope 2.1.X branch is not really being maintained.  You
should probably try to move to the latest release.

That said, it would be most helpful to have a full copy of the Zope
installation which exhibits the problem.  Even better (but probably less
possible) is to have a full copy of the Zope installation *right before*
the problem starts occurring and one *right after* the problem starts
occurring so we can look at the catalog data structures to see what
might be happening.  Platform is not thought to be an issue.  This would
be helpful even if it was a Zope 2.1.6 install.
