Good questions. Now I notice that it was added at the end (after resubscribing) as "Public-NIB/archive.older", but there's no other "/" appearing in the file! Other folders look like "Public-NIB.archive.2010a" or "INBOX.office" etc. I assume that folder originally had a "." instead of the "/" too.
If you want to know more history, I first used courier-imap, and later converted to dovecot 1.1, and even later to 1.2. I guess dovecot 1.1 was more lenient?
I think what happened was that you switched namespace separator from "." to "/", which then caused these prefixes to change in subscriptions file from Public-NIB.* to Public-NIB/*. It's actually kind of an accident that those Public-NIB.* entries in the subscriptions file even work.. It wasn't intended to work that way. Subscriptions for subscriptions=no namespaces are handled in a bit kludgy way. So, this isn't really a bug. :) Maybe some day in future separator changes can be handled better for subscriptions=no namespaces..
