[Dovecot] LIST-STATUS issue

[Michael M Slusarz]

Looked at the hg commits since 2.1.1, but didn't see anything that was  
exactly on-point to this...

UNSEEN counts seem to be broken when done in a LIST-STATUS call.  I  
see this, for example:

>> Timestamp: Thu, 01 Mar 2012 10:55:47 -0700
[...]
C: 3 LIST "" (INBOX IN.dovecot) RETURN (STATUS (UNSEEN))
S: * LIST () "." "IN.dovecot"
S: * STATUS "IN.dovecot" (UNSEEN 0)
S: * LIST () "." "INBOX"
S: * STATUS "INBOX" (UNSEEN 3)
S: 3 OK List completed.

3 seconds later...

>> Timestamp: Thu, 01 Mar 2012 10:55:50 -0700
S: * OK [CAPABILITY IMAP4rev1 LITERAL+ LOGIN-REFERRALS ID ENABLE  
AUTH=LOGIN XIMAPPROXY] Dovecot ready.

S: 2 OK [READ-ONLY] Select completed.
[...]
C: 7 SEARCH RETURN (COUNT) UNSEEN
S: * ESEARCH (TAG "7") COUNT 8
S: 7 OK Search completed (0.000 secs).

I can confirm that I did not receive 8 dovecot list messages in 3 seconds. :)

Once the mailbox is accessed, I am seeing correct counts in  
LIST-STATUS return again:

>> Timestamp: Thu, 01 Mar 2012 10:57:28 -0700
[...]
C: 3 LIST "" (INBOX IN.dovecot) RETURN (STATUS (UNSEEN))
S: * LIST () "." "IN.dovecot"
S: * STATUS "IN.dovecot" (UNSEEN 8)
S: * LIST () "." "INBOX"
S: * STATUS "INBOX" (UNSEEN 3)
S: 3 OK List completed.

I am using imapproxy for these connections, so all access are  
happening in the same Dovecot access.
