[ZODB-Dev] Urgent - Error ZODB zope 2.3.3

[Bruno Mattarollo]

Hi! It's me again!

Well, no luck so far. After running fsrecover for 8 hours and not finding
errors on the Data.fs file, I still get the state error! I placed the
Data.fs file on a Zope 2.5.0 installation and run the python console
script (import Zope and app = Zope.app() etc etc) and I get this error:

Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/home2/zope/cybercentre2/zope2.5.0/lib/python/ZODB/Connection.py",
line 471, in setstate
    state = unpickler.load()
  File "/home2/zope/cybercentre2/zope2.5.0/lib/python/ZODB/Connection.py",
line 132, in _persistent_load
    oid, klass = oid
ValueError: unpack tuple of wrong size

What should I do now? Does this means that there is NO way to go back?
What does this error mean? As I said before, I already run fsrecover and
discovered NO errors ! :(

Thanks for any other advise!!
