[Zope] Recovering zope data

[Corey Ralph]

i have just had a power outage and lost a fair amount of work on a test server.
As it isn't a production server, it had no UPS. 

Zope won't load, it gives me:

Traceback (innermost last):
  File lib/python/ZPublisher/Publish.py, line 877, in publish_module
  File lib/python/ZPublisher/Publish.py, line 325, in publish

ImportError: ('DatabaseError', 'Corrupted data record at 1156286')

Has anyone had any experience with this kind of thing?  Is there any chance I
can fix it?
