[Zope-dev] Weird "couldn't load state" on Zope 2.6.2

[Chris Withers]

Hi there,

When I click on the Advanced tab of one of my ZSQL Methods, I see this:

Traceback (innermost last):

Could not load oid XXXXXXdF, pickled data in traceback info may 
contain clues.

Where the XXXXXX in XXXXXXdF are what my mailer is substituting for unprintable 
characters.

And in in the event log I see:

I've never seen anything like this, and I'm certainly not using ZClasses.

Anyone got a clue what's going on?

cheers,

Chris
