Going on holiday tomorrow and trying to finish some actual work things
in a rush.

I wouldn't really know how to reproduce it again but Phillipp hinted
that it had something to do with changing from zope.app.session to
zope.session so I guess the way to reproduce it would be to start a
project which uses zope.app.session, then create some ZODB content,
then upgrade to 0.12.1 which I suspect uses zope.session instead.
I can try to make that a formal process to make a bug report out of it.
