[Zope-dev] Most likely explanation for pickling error ?

[Dr. Ross Lazarus]

A product, Zope 2.1.0b2 - when I try to add an instance, I get :-



Error type: cPickle.PicklingError
Error value:: Cannot pickle objects.
Error Traceback: Traceback (innermost last):
File /u2/home/rossl/zope21b/lib/python/ZPublisher/Publish.py, line 169,
in publish
File /u2/home/rossl/zope2/lib/python/ZODB/Transaction.py, line 237, in
commit
File /u2/home/rossl/zope2/lib/python/ZODB/Connection.py, line 325, in
commit
(Info: (('Products.foobar.foobar', 'foobar'),
'\000\000\000\000\000\002\\\355', ''))
cPickle.PicklingError: Cannot pickle objects.

Any suggestions as to what sort of python misdemeanor might be
responsible gratefully received?
