Dovecot 2.3.0, Panic: file mailbox-attribute.c: line 362 (mailbox_attribute_get_stream): assertion failed: (value_r->value != NULL || value_r->value_stream != NULL)
Hi at all, I have a RHEL7 server with Dovecot 2.3.0 (new installation). I've a problem when trying to dsync from a Dovecot 2.2.24 server.
If I try to sync any user with a folder with ACL, dsycn crash with panic:
Source server:

Coredump and configuration attached.
On source server I run this command:
# doveadm -D backup -f -u USERNAME -x 'Archives*' tcp:DEST_SERVER.example.com
but same panic if try to sync from destination server:
# doveadm -D backup -fR -u USERNAME -x 'Archives*' tcp:SOURCE_SERVER.example.com
Same panic also syncing any user with acl and using different acl_shared_dict (file or fs:posix) in dovecot configuration.
Thanks, Marco

Hi,
If I downgrade to Dovecot 2.2.33.2, there are no problems to sync users with ACL
Thanks, Marco
