[Zope-dev] Z2.7 & ValueError: Cache values may only be in one cache

I'm getting tracebacks like the following under Zope 2.7b1, but not in
Zope 2.6b5. Can somebody please shed some light on what this error is
trying to tell me, so I can work out if this is a Zope 2.7 bug or
my own fault?

Traceback (innermost last):
   Module ZPublisher.Publish, line 102, in publish
   Module Zope.App.startup, line 220, in commit
   Module ZODB.Transaction, line 233, in commit
   Module ZODB.Transaction, line 348, in _commit_objects
   Module ZODB.Connection, line 427, in commit
    - __traceback_info__: (('BTrees.IOBTree', 'IOBucket'), 
'\x00\x00\x00\x00\x00\x00\x00G', '')
ValueError: Cache values may only be in one cache.

The problem is intermittent.
