dovecot - Apr 2009 - Timeout leak with dovecot version dovecot1.2(8985:f43bebab3dac)

This is 64bit AIX 5.3. Looking through previous versions of dovecot, I see 
this warning. I didn't realize this was something bad until today.
My environment uses mbox/mbox-snarf plugin.

The message in the logs is:

local0.log.20090429:Apr 29 12:41:16 hostname dovecot: 
IMAP(jsiegle): Timeout leak: 1100054c0

In dbx(the AIX debugger) I see:

$ dbx imap
Type 'help' for help.
reading symbolic information ...
(dbx) gotoi 0x1100054c0
Goto address is not within current function or block. (set $unsafegoto to 
override)
(dbx) set $unsafegoto
(dbx) gotoi 0x1100054c0
stopped in cmd-append. at 0x1100054c0
0x1100054c0 (???) 00000001       Invalid opcode.
(dbx) where
cmd-append.() at 0x1100054c0

If you need more info, don't hesitate to ask.

Thanks,
Jonathan

It's not exactly bad. It gets logged only when the process is exiting.
But it shouldn't be happening either.

How easily can you reproduce this? For example if you do:

telnet localhost 143
1 login user pass
2 select inbox
3 logout

Does it get logged? What if you select some other mailbox instead?

I don't think this is correct, because there are no timeout callbacks in
cmd-append.c.
