Hi Ed. Thanks for the bug report! This looks similar to #1670, so I added a comment to that ticket pointing to this thread. I also marked the bug as important and as threatening data-preservation. I'm sorry that I can't work on this bug more right now, but I'm very busy preparing for an imminent commercial launch of our ciphertext storage service.
If any hacker out there wants to earn great gratitude from Ed and many other users, study this bug report and figure out how it is happening!
