Please describe the problem:
I'm connecting to my email server using IMAP.  The structure of my mailboxes is as follows:
  inbox
  sent-mail
  draft
  trash
  spam
  archive---->work
          |-->school
          |-->home

In Folders-->Subscriptions..., the only choice is 'inbox' and I am therefore unable to subscribe to any of the other mailboxes.

Steps to reproduce:
1. Create mailboxes at same level in hierarchy as inbox on server.
2. Folders-->Subscriptions...


Actual results:
Only 'inbox' appears in folder list.

Expected results:
All of the folders that are being exported on the mailserver should appear.

Does this happen every time?
Yes.

Other information:
I enabled logging (export CAMEL_VERBOSE_DEBUG=1) and, after launching evolution from the terminal (evolution --debug=evo.log &) I observed the following:

sending : A00002 NAMESPACE
received: * NAMESPACE (("mail/" "/")("" "/")) NIL NIL
received: A00002 OK Namespace completed.
sending : A00003 LIST "" INBOX
received: * LIST (\HasNoChildren) "/" "INBOX"
received: A00003 OK List completed.

After reading RFC 3501 and RFC 2342, it's not apparent to me why A00003 has "INBOX" as the mailbox name.  It appears that it's assuming a certain directory structure when it should be able to query the server for that information instead.
