dovecot - Mar 2005 - Namespaces and subscriptions

I've got a problem with subscriptions in 1.0-stable when migrating from 
UW-IMAP.

I've modified the SUBSCRIPTION_FILE_NAME entries as suggested in the 
Wiki http://wiki.dovecot.org/Migration and included the "~/mail/" etc.
hidden namespaces.

The .mailboxlist files contain entries like "~/mail/somefolder" and
the
clients have "~/mail/" set as a prefix.

In UW-IMAP:

xyz LSUB "" "*"
* LSUB () "/" ~/mail/somefolder
xyz LSUB "~/mail/" "*"
* LSUB () "/" ~/mail/somefolder

Now with Dovecot:

xyz LSUB "" "*"
* LSUB () "/" "~/mail/somefolder"
xyz LSUB "~/mail/" "*"
* LSUB () "/" "~/mail/~/mail/somefolder"

In other words, Dovecot is prepending the namespace to the list of 
folders stored in .mailboxlist.

This causes Thunderbird to show the folders as 
-~
 - mail
 | somefolder

which are accessible. Squirrelmail gets completely confused and tries 
to display "~/mail/~/mail/somefolder" (but works with the prefix set
to
"").

Am I missing something? I tried Geo's empty namespace patch, just in 
case that would help, but it didn't.

Best Wishes,
Chris

I've got a yucky workaround that doesn't prepend the namespace when 
listing subscriptions and the namespace is marked as hidden:-

        while ((list = mail_storage_mailbox_list_next(ctx->list_ctx)) !=
NULL) {
                str_truncate(name_str, 0);
-               str_append(name_str, ctx->ns->prefix);
+               if (!(ctx->ns->hidden && ctx->lsub))

                str_append(name_str, list->name);

                if (ctx->ns->sep != ctx->ns->real_sep) {


This at least means that UW-IMAP refugees don't need to update their 
subscriptions or change their prefix.

Perhaps we need another namespace option, or is there a better way? 

On a related subject, would it be a good idea to make the 
SUBSCRIPTION_FILE an option in the same way that INDEX=, CONTROL= etc. 
are?
