Hmm.. I am not sure what goes on here, but I suspect that mysqlUserFolder
is at fault here. It seems it (or another faulty product) stores wrapped
objects in the ODB, and IIRC this shouldn't happen.
To be honest, I have never looked deeply into the voodoo that is

There are a few tools for analysis and recovery:
- fsrecover.py, which can be found in lib/python/ZODB of a Zope
distribution, repairs damaged Data.fs files. Start with python
- tranalyzer (http://www.zope.org/Members/tsarna/Tranalyzer) let's you
look athe contents of a ZODB, in real time if necessary.
However, this is a problem with a correct pickle, but the class needed for
the unpickling isn't available. ImplicitAcquirerWrapper can never be
imported from Acquisition however.
