dovecot - Aug 2008 - Problems with namespaces

Hi, 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 /Tom

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 {

location = maildir:/vmail/%Ld/Shared:INDEX=/vmail/%Ld/%Ln/Shared

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?
