dovecot - Sep 2012 - doveadm backup - Fatal: All your namespaces have a location setting.

Hello list,

I am using dovecot v2.1.9 and have a problem with doveadm backup:

# doveadm backup -u user at domain.com 
maildir:/backup/domain.com/user/Maildir
doveadm(user at domain.com): Fatal: All your namespaces have a location 
setting. It should be empty (default mail_location) in the namespace to 
be converted.

Here my namespace config:
namespace {
   list = children
   location = 
maildir:/var/vmail/%%d/%%n/Maildir:INDEX=/var/vmail/%d/%n/shared/%%u
   prefix = Gemeinsame-Postfaecher/%%u/
   separator = /
   subscriptions = no
   type = shared
}
namespace inbox {
   inbox = yes
   location = 
maildir:/var/vmail/%d/%n/Maildir:INDEX=/var/vmail/indexes/%u
   prefix    separator = /
   subscriptions = yes
   type = private
}

Have I got a problem with my namespace config?

Regards,
Tobias Hachmer

Different installations use different kinds of namespaces for different
purposes, so dsync can't simply sync all the namespaces. It syncs only the
namespace which uses the global mail_location setting (not overriding it by
having an explicit location setting).

So you probably should remove this location setting (and make sure mail_location
is the same).
