[Dovecot] virtual plugin and shared namespace

[l.chelchow...@eurocar.pl]

Hi,

I have a problem with virtual plugin and geting mails form shared 
namespace.
dovecot-virtual:
----
Shared/*
Public/*
*
    unseen
----
dovecot.conf:
----
namespace {
  inbox = yes
  location =
  prefix =
  separator = /
  type = private
}
namespace {
  list = children
  location = 
maildir:/home/vmail/public/:CONTROL=/var/mail/vmail/%d/%u/control/public:INDEX=/var/mail/vmail/%d/%u/index/public:LAYOUT=fs
  prefix = Public/
  separator = /
  subscriptions = yes
  type = public
}
namespace {
  list = children
  location = maildir:%%h/:INDEX=/var/mail/vmail/%d/%u/index/shared/%%u
  prefix = Shared/%%u/
  separator = /
  subscriptions = no
  type = shared
}
namespace {
  list = children
  prefix = Virtual/
  separator = /
  location = virtual:~/virtual
}
----

When I enter the virtual mailbox Unread I get this debug info:
virtual mailbox Virtual/Unread: Skipping non-existing mailbox 
Shared/t...@domain.pl/

Is it a bug or misconfig?
