cyrus-imap response not RFC compatible

[Alain Spineux]

Hi

I got the following answerer to the LIST command  (this is ascii tcpdump
log, the full session is at the end)

22:23:23.157240 IP box17.47347 > fc6-eg.imap: P50:67(17) ack 317 win 216
<nop,nop,timestamp 109340393 175020224>
EKDA2 LIST "" *..
22:23:23.171070 IP fc6-eg.imap > box17.47347: P317:328(11) ack 67 win 181
<nop,nop,timestamp 175020226 109340393>
31 lockers.
22:23:23.175567 IP fc6-eg.imap > box17.47347: .328:3224(2896) ack 67 win 181
<nop,nop,timestamp 175020229 109340393>
* LIST (\HasNoChildren) "/" "user/admin.aa.loc at aa.loc"..
* LIST (\HasNoChildren) "/" "user/catchall.aa.loc at aa.loc"..

The Wron line is "31 lockers."

First, 31 in not a valid TAG for the session,
second the line end by '\n' and not by both CRLF

I looked the sources, their is no "locker(s)" string that could be send that
way!
I suspect the line is coming from a berkley DB error message.
This error append only when 2 or more processes are searching the same
mailbox.

Any idea?

Here is the full session  transcript:
