Because it was built without debugging symbols, I think this is all I
can get for you.

I've dropped this database and restored it from backups to get it
running again. But I've also kept a copy of the erroneous data for
bug-hunting purposes. If you'd like to track this down and/or find a way
to automatically clean up data corrupted in this fashion, I'll be happy
to work with you. If you have no interest, please let me know so I can
delete the files.
