I know this problem when I have an inconsistency between
our own "Transience" implementation or the stock
"Transience" implementation on which it builds.

Almost surely, this is not the reason for you.
But maybe, you, too, have either a code or code/data inconsistency?
Did you make a clean install of "Transience"?
Do your session data lives in a RAM storage (default) or
in a FileStorage?

Apparently, your session data lives in a long living
storage (not RAMStorage) and the session pickles there
lack some information which is not relevant.

Shut your Zope down and discard all existing session data.
