Darn.  At this point you can try just hacking off bits of file at the 
end of a *copy* of the Data.fs you have by using the trunctate method 
described in Itamar's howto.  Start small and just cut off pieces at the 
end of the file until you're able to start Zope again.  You might lose 
some data this way but at least it will start.  After you get it to 
start, and you've lost data, you can also use (painfully slow) binary 
search to pinpoint where exactly you need to truncate on further copies.

I am working on preventing this on the 2.5 branch now.

It's ironic that I got on Jeremy's case for something like this not too 
long ago. ;-)  Mea culpa.
