If you want to pursue this further, I suggest getting a hold of the
database record (e.g. using our friend the debugger) and running it
through one of the xml pickle variants
to see if you get any additional clues about what's going on.
Sorry I can't be more helpful, but I would have to spend time looking
a the specific case and I can't spend that time.
