[Dovecot] 2.2beta2: LSUB broken

[Lutz Preßler]

Hello,

I have some problems with (listing) subscriptions on my test system
running 2.2beta2 (compared with 2.1.15, configuration and Maildir content
unchanged):

With 2.1.15:
0 lsub "" "*"
* LSUB () "." "INBOX.Trash"
* LSUB () "." "INBOX.in2009"
* LSUB () "." "INBOX.test"
* LSUB () "." "INBOX.test.test2"
* LSUB () "." "INBOX.in2010"
* LSUB () "." "INBOX.in"
* LSUB () "." "INBOX.virtual.small"
* LSUB () "." "INBOX.virtual.sent"
* LSUB () "." "INBOX.virtual.allin"
* LSUB () "." "INBOX.virtual.week"
* LSUB () "." "INBOX.virtual.gmail"
0 OK Lsub completed.

With 2.2beta2 (output of doveconf -n attached):
0 lsub "" "*"
0 OK Lsub completed.

... empty list. Same with "list (subscribed)".

After disableing the "virtual" namespace in the config, it gets:
0 lsub "" "*"
* LSUB () "." Trash
* LSUB () "." in2009
* LSUB () "." test
* LSUB () "." test.test2
* LSUB () "." in2010
* LSUB () "." in
* LSUB () "." INBOX.Trash
* LSUB () "." INBOX.in2009
* LSUB () "." INBOX.test
* LSUB () "." INBOX.test.test2
* LSUB () "." INBOX.in2010
* LSUB () "." INBOX.in
0 OK Lsub completed.

Note mailboxes listed with and without INBOX. prefix.

Thanks,
  Lutz
