Any idea how to reproduce this? Dovecot catches this error a bit too
late for the backtrace to be useful. What plugins do you use?
Anyway this isn't too bad because the client had already disconnected.

User has a huge mailbox, probably the client runs into a timeout and disconnects.

Instead of spending effort on priority queueing, make the system drain the queue faster for all mail...

No, the user logged in normally using LOGOUT command (cmd_logout() is
called). Hmm. Maybe the client is trying to pipeline commands and
issues a logout while another command is still running. Any idea what
the client is?

Mutt also pipelines the logout, usually with a CLOSE.

Well, I committed a change that might fix this: http://hg.dovecot.org/dovecot-1.1/rev/0917df31efec
I'll check it properly later.
