And i really don't know what's going on here. Is it possible they get re-encrypted at some time, maybe when you change anything else in the account (like switch from STARTTLS to SSL or so) ? Or in the process of down- and re-upgrade ? Like, some claws key/Cert has changed ? What if the mailbox providers cert change, could it trigger re-encryption ?

They get reencrypted anytime you change a password (just that
particular password gets reencrypted), or enable/disable master
passphrase (all passwords get reencrypted).

I think in your case it was your downgrade followed by an upgrade. When
writing the migration routine, I did not really think to handle someone
doing that kind of craziness.
