[Zope] NameError instantiating ZClass instance, but it used to work!

[Brad Clements]

Running Zope 2.3.3 on RH Linux 7.1

I created a Product with 3 Zclasses.  2 of the 3 Zclasses work okay, but one of them 
raises a NameError during the add process saying that it can't find the ZClass itself, 
even though the darn thing is listed in the Product folder. (Also, Monitor Client shows it's 
there too, see below)

>From ZMI, selecting Add "Searchable Company", then entering the ID results in the 
traceback.

I'm totally stumped trying to fix this, anyone have any ideas how to figure this out?
I tried exporting to XML and re-importing the Product (after deleting it) but the XML 
import process raises an Exception (not enough args passed).

I tried export/reimport in .zexp format, but the results are the same.

This is a standard ZClass that is based on ZObject, _ZClass_for_PortalFolder, 
_ZClass_for_DefaultDublinCoreImpl. (and 1 other Zclass in this product has the same 
base classes)

It *used* to work, but today I find that I can't create any more instances.

Using ZMI, I get this:

Error Type: NameError
Error Value: SearchableCompany

And from within CMF, I'm getting an "Unauthorized" exception trying to add an instance 
through invokeFactory, even though I'm logged in as Manager.

Using the CMF and adding an instance to My Stuff, I get this:

You are not authorized to access SearchableCompany.

addSearchableCompany is a Python script with this line:

return context.manage_addProduct['SearchableCompanies'].SearchableCompany.createInObjectManager(id,context.REQUEST)

And using Monitor client I AM able to get at SearchableCompany within the Product
