the stray byte would be more likely in the memory/disk cache as you
didn't intend to remove a stray byte, you removed an entirely innocent
field, and that could have perturbed your file off of a bad patch of
disk or some such.
If you still have the file in the un-openable form I would be very
interested to see it (confidentiality respected!). (If you *do* still
have it, try and make a copy and open that...).
