Hi,
I can confirm this is often caused by corrupted Data.fs. Other potential
causes are bad rsync transfers.
http://collective-docs.readthedocs.org/en/latest/troubleshooting/exceptions.html#valueerror-non-zero-version-length-versions-aren-t-supported
sauna.reload increases your changes of corruption Data.fs as it forcefully
restarts Zope instance very often and makes other bad things happen. I
suggest you run sauna.reload in new ZEO mode (client + db) in which case
the database process stays intact between restarts.
