We use it without problems.

However, I would not say I were a ZEO expert...

Yes, but this should not cause big problems;
especially, Zope looking at the "Data.fs" directly should have the
same problems than ZEO looking at the same "Data.fs".
You may run "fsrecover" on your "Data.fs" (in the ZODB package)
and see whether it finds something strange.

A mystery...

The problem might be some corrupted "pyc" file belonging to
the ZEO server.

   We once had a mysteriously truncated "*.pyc" file
   leading to weird and difficult to explain errors.

   Maybe, you remove all "*.pyc" files and restart ZEO/Zope.

The fact, that some variables contain "None" whereas they should
contain a function, does not indicate a "Data.fs" problem but
some code problem.
