It seems the culprit may be procmail which breaks. But only when I am
logged on my imap account.
When I am logged on imap, a verbose procmail gives:
$ procmail </dev/null 2>&1
procmail: Couldn't create "/var/mail/n"
procmail: [5957] Tue Jul 18 16:04:16 2006
procmail: Assigning "LOCKFILE=/home/n/procmail.lock"
procmail: Locking "/home/n/procmail.lock"
procmail: No match on "^Return-path:.*exim-users-bounces.*"
procmail: No match on "^Return-path:.*dovecot-bounces.*"
procmail: Couldn't create or rename temp file "/home/n/Maildir/new/msg.eW3"

When not logged into my imap account, it all works well:
$ procmail </dev/null 2>&1
procmail: Couldn't create "/var/mail/n"
procmail: [3092] Tue Jul 18 16:06:03 2006
procmail: Assigning "LOCKFILE=/home/n/procmail.lock"
procmail: Locking "/home/n/procmail.lock"
procmail: No match on "^Return-path:.*exim-users-bounces.*"
procmail: No match on "^Return-path:.*dovecot-bounces.*"
procmail: Assigning "LASTFOLDER=/home/n/Maildir/new/msg.R33"
procmail: Opening "/home/n/Maildir/new/msg.R33"
procmail: Acquiring kernel-lock
procmail: Notified comsat: "n at 0:/home/n/Maildir/new/msg.R33"
  Folder: /home/n/Maildir/new/msg.R33
      1
procmail: Unlocking "/home/n/procmail.lock"

Note that I used a static lock to test. But it seems that dovecot is
doing something with the file /home/n/Maildir/new/msg.R33 very likely
moving, deleting or renaming it as I cannot find it back afterwards.
