fsrecover.py runs without complaint, fstest.py runs without complaint. 
fsrefs.py complains about two (new) objects before dying with the same 
error.

This is after I've used a script I wrote that cobbled together various 
other suggestions for finding and deleting broken objects.

The pack fails with an unpickling error, every time, on the same object. 
  Unfortunately it gives me no indication as to what object is so 
horked; no OID, no nothing.

I'm not sure how to proceed at this point; I guess I'd like to find some 
way to tell the pack operation "if you can't unpickle, seek forward 
until you find another header, and just don't bother with this one".

I don't know if that's the right way to approach it, but that's what 
occurs to me at the moment.
