INBOX subfolders not showing up

[Dr. Matthias Sitte]

Ok, just googled some more and came across this post [1]. It's basically
a very similar to mine, and describes the same problem that INBOX has no
subfolders. So, I've logged in with telnet to list the INBOX subfolders
as well:

=== SNIP ===
2 list "" INBOX
* LIST (\HasNoChildren) "/" "INBOX"
2 OK List completed.
=== SNAP ===

Duh. But everything else shows up:

=== SNIP ===

4 list "" "*"
[...]
* LIST (\HasChildren) "/" "Archives"
[...]
4 OK List completed.
=== SNAP ===

So, what just happened? According to [1], there's a bug in lib-storage
with LAYOUT=fs and non-mbox maildir format [2]. Is that correct? I have
to assume that it's not fixed in Debian's packaged version 2.1.7, right?

Can someone confirm that?
