[Dovecot] Panic: file mailbox-list-maildir.c: line 133: unreached
I converted personal mailboxes from maildir to sdbox. Public mailboxes
are still in maildir format, because I need per-user seen flags.
However, if the user is subscribed to public mailboxes and the client
sends 'LIST (SUBSCRIBED) "" *', dovecot crashes with:
