Hi Filippo,
   By coincidence I was also trying to install CMFEditions today, and 
got the exact same error. This was CMFEditions 1.1.2, (and I tried 
earlier 1.1 in case something in 1.1.2 had broken 2.5.x compatibility) 
Platform - Plone 2.5.3, Zope 2.9.8, python 2.4.4, Debian Etch.
   I did this on a copy of our live site which has a long history since 
2.0.x and a bunch of stuff installed. I had planned to next test this on 
a fresh empty Plone site.
   If you're doing this on an empty Plone site, then this sounds like a 
repeatable bug in CMFEditions.
   If it works on an empty Plone site, but works for neither of us in 
copies of our live sites, then I was wondering about whether the 
2.1->2.5.3 migration leaves something in a messed up state that 
CMFEditions install can't cope with. In particular GenericSetup, though 
I don't know enough about that yet.
Cheers
Nick
