dovecot - Oct 2010 - Upgrading from 1.2.8 to 2.0.6: INBOX not selectable in Thubderbird (greyed and italic)

I recently upgraded from 1.2.8 to 2.0.6, I am using Maildir, and 
Thunderbird is showing the INBOX grayed out and in italics, and does not 
show new messages in it (it shows messages previously downloaded). This 
occurs when Thunderbird is restarted (if I upgrade dovecot, TB keeps 
working fine until I shut it down, and at next startup it greys out the 
inbox). All the subfolders of INBOX work fine. Accessing with horde+imp 
webmail works fine. I'm using TB 3.1.6

After some traffic capturing, The first difference I see in the IMAP 
exchange is the answer to

6 list "" "INBOX"

Which for 1.2.8 is:
LIST (\HasChildren) "." "INBOX"

and for 2.0.6 is:
LIST (\Noselect \HasChildren) "." "INBOX"

Of course for the same user and same maildir. I enabled 
tb-extra-mailbox-sep in 2.0, but it doesn't appear to differ (I don't 
really think it should).

Any help will be very much appreciated. My 1.2.8 config for the 
namespaces is:

namespace private {
  prefix = INBOX.
  inbox = yes
  location = maildir:~/Maildir
}

namespace public {
  prefix = shared.
  location = maildir:/usr/local/shared
  list = yes
  subscriptions = no
}

And the config for 2.0.6 is the same with new syntax:

namespace {
  type = private
  prefix = INBOX.
  inbox = yes
  location = maildir:~/Maildir
}

namespace {
  type = public
  prefix = shared.
  location = maildir:/usr/local/shared
  list = yes
  subscriptions = no
}

Regards,

                                    Michele Bergonzoni

What errors are in your Tbird Activity Manager?  Those may be helpful.

Note that the auto update for 3.1.6 was just a day or two ago.  Is the
update a factor or merely coincidence?  Upgrading a server component as
client component simultaneously is a recipe for disaster WRT
troubleshooting problems: the proverbial finger pointing.

Yeah, that's wrong.

What about full doveconf -n output? I couldn't reproduce with just those
namespace settings.

(Sorry Timo, I replied to you instead of the list)

Well, this is a quite old system with 2.4 kernel and /lib/libc-2.3.1.so
(dating back to 2003). If this turns out to be the problem, shame to me
for not upgrading this beast.

Activity manager and error console are both completely silent.

You are perfectly right: I had the problem with 3.1.5, and upgraded it 
just before writing to the list. I also removed all the TB profiles in 
C:\Documents and settings, and deleted/created the account a few times.

Since Timo said it is not immediate to reproduce, I post the whole IMAP 
conversation up to that point:

* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE 
IDLE STARTTLS AUTH=PLAIN] Dovecot ready.

1 authenticate plain

CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH 
LIST-STATUS] Logged in

2 namespace

* NAMESPACE (("INBOX." ".")) NIL (("shared."
"."))
2 OK Namespace completed.

I hope I am not wasting your time on a problem affecting only systems of 
age > 8 years.

Thanks and regards to all,
