I still have some of my private keys in plaintext.  I would guess that BSDDB sometimes will "overwrite" data by just discarding a pointer to the old data, and writing the replacement to a new location within the file.  In that case, examining the file with a BSDDB library tool is not going to find this problem.  You'll have to examine the raw binary file as I did.  Instructions for verifying this problem are in the post.

Can someone please verify that this is a real problem?  (and should we maybe remove my post until there's a remediation plan?  This is problem the best kind of problem to disclose after it's fixed)
