Голубятня, не работающая с добавленным общедоступным пространством имен

мы выполняем Голубятню 2.2.5 под Сервером OS X 4.1 (под 10.10.3). Я пытаюсь добавить общедоступное пространство имен с некоторыми общедоступными папками без успеха.

Бит, который я добавил, был:

namespace public-junk {
  location = maildir:/Library/Server/Mail/Data/mail/public
  prefix = Public
  separator = .
  subscriptions = no
  type = public
}

После того, как я перезапускаю его и пытаюсь войти в систему, это указывает, что внутренняя ошибка произошла:

* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE XAPPLEPUSHSERVICE AUTH=CRAM-MD5 AUTH=DIGEST-MD5 AUTH=PLAIN AUTH=LOGIN] Dovecot ready.

* BYE Internal error occurred. Refer to server log for more information.

Однако нет действительно ничего в журнале, который кажется релевантным:

Кто-либо может видеть то, что я делаю неправильно или предлагаю, где я могу искать некоторую более ценную информацию?
