I didn't manage to write failing test (even thought I tried few 
different variants).
Even with just two products in instance: Five and ViewsTutorial, and 
folders
structure in ZMI I've described before I have errors.. but tests are 
passing.
The good news is that upgrading to Zope 2.8.8 solved this problem :)
Maybe it was something in my Zope2.8.6 core files but I tried this on
two different machines with the same effect...

<five:traversable class="OFS.Application.Application"/> did the thing

Thanks for your help!
