I've since discovered that the problem happens when altering the hidden 
state of the entry, or updating it while it is hidden.

If the entry is not hidden, then I can update it as much as I please 
with no errors. If I then hide it, and save the record, I get the same 
error. Any updates made while the record is hidden reproduce the problem.
