[Evolution] evo 1.4.5 with dovecot imap not showing subfolders

[Steve Baker <steve stevebaker org>]

I've just set up a dovecot imap server with the following folder
hierarchy:
INBOX
  Drafts
  Sent
  Trash
- adsf
    fdsa
- bar
    baz
  test1

This displays correctly with Squirrelmail but Evolution doesn't display
the subfolders fdsa and baz.

Here is the connection log

$ export CAMEL_VERBOSE_DEBUG=1

Creating a subfolder of asdf gives:
sending : A00017 SELECT adsf
received: * FLAGS (\Answered \Flagged \Deleted \Seen \Draft)
received: * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft
\*)] Flags permitted.
received: * 0 EXISTS
received: * 0 RECENT
received: * OK [UIDVALIDITY 1083922245] UIDs valid
received: * OK [UIDNEXT 1] Predicted next UID
received: A00017 OK [READ-WRITE] Select completed.
sending : A00018 LIST "" adsf
received: * LIST (\Children \UnMarked) "." "adsf"
received: A00018 OK List completed.
sending : A00019 CREATE adsf/qwer
received: A00019 NO Invalid mailbox name: adsf/qwer

So knowing nothing about IMAP it looks like Evolution is ignoring the
\Children and the "." folder delimiter.

This looks identical to the problem this guy is having:
