[Dovecot] Saving mails to +detail failed: Namespace error

[Peer Heinlein]

We have the following namespace:

namespace {
  inbox = yes
  list = yes
  location = 
  prefix = INBOX/
  separator = /
  subscriptions = yes
  type = private
}
namespace {
  list = children
  location = maildir:%%h:INDEX=%h/shared/%%u:CONTROL=%h/shared/%%u
  prefix = shared/%%u/
  separator = /
  subscriptions = yes
  type = shared
}

and we set:

lmtp_save_to_detail_mailbox = yes
recipient_delimiter = +

But sending Mails to user+detail is failing:

But a folder named "Cong" exists:

What's going wrong? My mistake or is it a bug?
