[Dovecot] Doveadm sometimes failed "to iterate through some users" after upgrade to 2.2

Yes, after an upgrade works fine.

Hello,

Unfortunately this issue hits again. I installed the latest stable version 2.2.15 and got the following error

# doveadm expunge -u "^o^@dave.s484.qa-team.net" mailbox 'INBOX.Junk Mail' SAVEDBEFORE 7d doveadm(^o^@dave.s484.qa-team.net): Error: userdb lookup(^o^@dave.s484.qa-team.net): Disconnected unexpectedly doveadm(^o^@dave.s484.qa-team.net): Fatal: User lookup failed: Internal error occurred. Refer to server log for more information.

# echo $? 75

Our production servers run 2.2.13, where the situation is the same.
