Interesting...

Several Plone users (3 within the last 6 weeks or so)
reported similar behaviour.
Apparently, there is some hole which leads to inconsistent
writes especially in the Plone environment.

Hopefully, you did not yet pack your "Data.fs" (or have
the original "Data.fs.old" still around).

Please try to compress your "Data.fs" (or "Data.fs.old", in case
your have packed) with "bzip2". If the result is not much bigger
than about 100 kB, you send me the "Data.fs.[old.]bz2" for analysis.
