[Zope] pickled data in traceback

[Chris McDonough]

THis looks like you have an object in your database that still wants the
Zclass definition (or base class definitions) for SQLMemberFolder, which is
evidently part of the PTK.

You'll need to determine which object(s)in your object database still needs
this class.  This can be hard, especially if you don't know the answer
already.  :-)

The first step is probably to reinstall the Product it's complaining about.
In your case, this would probably be the revision of the PTK that used this
class.  Then track down the offending objects basically through trial and
error (remove any instances which obviously depend on the product).

If that doesn't work, it's time to bring in the big guns, which means
looking up oids in the debugger, which isn't something for the faint of
heart.  Sorry I don't have better news, nor the time to explain how to do it
(because I'd need to puzzle it out myself).

This problem really needs to be addressed in a better way, as it's very
common.
