dovecot - Sep 2010 - inbox doesn't exist, and quota calculation error

Perhaps related to the other errors I just reported, I also see a few of these
in the dovecot-2.0.3 logs:
lda(pid 8212 user user3): Error: Opening INBOX failed: Mailbox doesn't
exist: INBOX
lda(pid 8212 user user3): msgid=<201009240906510365.1gj1fpfhrhhm9 at
mail>: save failed to INBOX: Mailbox doesn't exist: INBOX
lda(pid 8212 user user3): Error: BUG: Saving failed to unknown storage

and some clients report receiving this IMAP error:
tag NO Mailbox doesn't exist: INBOX

although in general mail delivery and IMAP work, and these users' Maildir++
directories do exist and look OK.  This error did not occur for the user1 or
user2 in the other report.


And here's a third kind of error:
imap(pid 5722 user user4): Error: stat(/path/to/mail/user4/tmp/?) failed: No
such file or directory
imap(pid 5722 user user4): Error: Internal quota calculation error

That path looks like a memory munge.

For newly created users that don't have the Maildir directory created
yet? I guess there could be some race condition there in the initial
INBOX creation.. This is with normal mail_location=maildir:~/Maildir or
something?

I think that happens only once and afterwards the INBOX is created and
stuff works ok?

Yeah, it does look like some memory corruption or something. And yeah,
possibly also related to that filename="" bug. This is with Maildir++
quota? Did OSX have valgrind yet (or do you have something equivalent)?

This was caused by the lost tmp/ directories, which was fixed by that
patch I sent. Also http://hg.dovecot.org/dovecot-2.0/rev/5b0a1974fc6f
fixes recreating these missing tmp/ dirs.
