Ok, thanks.

I tried some different registrations they worked,
but theres a bug in the registration framework.

You can try this if you register two 
BrowserCookieIdManager, the second time you get a 
UnpickleableError: Cannot pickle 
<type 'zope.security._proxy._Proxy'> objects

I think there are a psecurity proxied object somewhere?

I don't know if this is known bug and it's a part of the next 
release.
