[Dovecot] Problems with namespaces

[tomzu at buu.lv]

Sorry, my previous post looked like sh.. (due to html I guess)

I'm trying to create Shared folder with subfolders "SPAM" and "NOT_Spam".

Configuration:
namespace public {
separator = /
prefix = Shared/
location = maildir:/vmail/%Ld/Shared:INDEX=/vmail/%Ld/%Ln/Shared
hidden = no
}

Result I get (is exactly what I want):
Inbox
Drafts
Sent
Trash
Shared
--NOT_Spam
--SPAM

I can select SPAM and NOT_Spam, delete messages etc, but when I select
"Shared", it shows: "Mailbox doesn't exist: Shared." As a client I used OE
and Thunderbird. How to get rid of that message?

I'm running latest Dovecot release 1.1.2
