   zope.app.session = 3.4.2

to buildout.cfg AND


to setup.py made it possible to use the application management view  
again and also to login to my application.

I am still getting the IRole.__iro__ attribute error when trying to  
access my other views. I have tried with zope.app.session==3.5.1 but  
to no avail.
