Bug Report - Crash on imap with core dump - Alternate storage related

I would like to report a bug we are seeing on an new deployment here:

Linux: Debian Jessie, inside a Docker container
Dovecot version: 2.2.23 (806d709) / 2.2.23-1~bpo8+1
doveconf -n: http://pastebin.com/2xA2xuRw
Filesystem: CephFS - Jewel

After migrating our users from our old server to our new one we can't
access a few mailboxes. Backtrace follows:

One important info is that I used to use Alternate Storage on the older
servers, but the not on the new one. Code seems to be trying to move a
message to an alternate storage that doesn't exist.

doveadm dump dovecot.index will show that we still have the
ALTERNATE_STORAGE flag set:

root at dovecot:/srv/dovecot/mail/
mav.com.br/daniel.colchete/mailboxes/INBOX/dbox-Mails# doveadm dump
dovecot.index|grep RECORD|head

Thank you very much.
