[Zope] Corrupt Data.fs

[Tim Terlegård]

Zope/python process borked, so I kill -9'd it. Now it seems like
that broke a few things in zodb. Zope will start up though and
most things are OK.

So I executed fstest.py and got this output among others:
862903 object serialno 0x034ab50f9b84f008 does not matchtransaction id
0x034ae7d 5858d5455

So my assumption is that something is wrong with the database,
so I wanted to run fsrecover.py:

lib/python/ZODB# python fsrecover /tmp/Data.fs /tmp/newData.fs
Traceback (most recent call last):
...
File "/usr/local/Zope/lib/python/ZODB/Connection.py", line 50, in ?
    ExtensionKlass=Base.__class__
AttributeError: __class__

I'm not able to run fsrecover. I use Zope 2.6.2 - what should
I do? Are there better recovery tools?
