Actually, the incompatibility arises because zope.session requires
zope.i18nmessageid >= 3.4.3 (it won't work with an older one) but
completely fails to declare so in its setup.py (there, it says it
required zope.i18nmessageid, but without any lower version constraint).
So there's actually a bug in zope.session here.
