This has become a FAQ now: you have pickles that refer to
zope.app.session, but the code was now moved to zope.session. Even
though zope.app.session has backward-compatibility code for this case,
your application probably no longer pulls in zope.app.session because it
has no apparent dependency to that package. Workaround: make your
application depend on zope.app.session and it should work again.
A similar problem may occur with zope.app.securitypolicy as well.

We should release a grok 0.12.2 that fixes this problem by depending on
zope.app.session and zope.app.securitypolicy again.
