I noticed this :)

Says "There are no non-empty versions."
Seems I'm not lucky.

Seems that it's the case...
I made a new Zope 2.6.2 instance, with the same products, then copied the
Data.fs to that new instance. That new instance refuses to start : raising
the same exception, then stopping (panic mode).

Do you think that starting a new Zope 2.6.2 instance with the same products
and a virgin Data.fs then exporting/importing all folders at root as zexps
would fix this ?

$ python utilities/ZODBTools/fstest.py -v var/Data.fs
var/Data.fs truncated possibly because of damaged records at 1117825536

But I dunno how to fix this...
