[Zope] Data.fs contains corrupted transaction

I have a Data.fs file containing a corrupted transaction. Unfortunately, about 3 days of postings were lost from technocrat.net, fiawol.com, and squishdot.org because of this. Would anyone like to look at the file and see if there is some Zope bug involved? Also, is there any way to recover the file? If it can be made usable, I can bring it up in a separate Zope instance and copy some objects over to my regular Zope instance. Thanks Bruce Perens
