UPD: 2.2.27 : accessing "mdbox_deleted" content destroys indexes

[Benoit Branciard]

Just to say this bug is still present in 2.2.27 (1:2.2.27-2~bpo8+1
jessie-backports Debian package).

# dovecot --version
2.2.27 (c0f36b0)

mail_location = mdbox:~/mdbox:DIRNAME=_@@_dbox-Mails_@@_

Please let me know if you want me to transmit our "doveconf -n" output.

Regards,
