doveadm quota recalc returns a Segmentation fault

Hi,

with the latest dovecot-ee version (2.2.25.4 (5cb7c97)) if I run “doveadm quota recalc -u alessio@skye.it” dovecot return a “Segmentation fault” (but the quota is update fine). Since dovecot version 2.2.24.3 (55cdc32) works fine.

This is my quota backends configuration:

plugin { quota = maildir:UserQuota quota2 = dict:Quota Usage::noenforcing:proxy::sqlquota } dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext }

I found that if I comment the line “quota2 = dict:…” doveadm quota recalc works fine. I have two quota backends because with dict I can store everybody's current quota usage in a SQL database for fast retrieving (like quota_clone plugin but I cannot switch to it immediately).

The backtrace:

I hope can be fixed. Thanks
