[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:

This does not happen with 'LSUB "" *' or with personal mailboxes in maildir format.
