That's right.  Sorry that the wink didn't convey that clearly.  I'm
looking at it now, but it seems clear that Tim will need to take a look.
As far as I can see, there is definitely something wrong with the
pickle.  I can't unpickle it with either Python 2.3 or 2.2; they both
fail the same way.  I don't know why Zope is behaving differently for
you with different versions.

Since I can't unpickle the pickle, I expect there's something wrong with
the code that wrote it.
