dovecot - Sep 2012 - Dovecot deliver Segmentation fault when arrive the first message

Hi,

I have found this strange problem. I'm working with Debian 6, dovecot 
2.1.9 and vpopmail-auth.

LDA is configured and works fine but the problem is when the first 
message arrive "dovecot-lda" return a "Segmentation fault",
the message
is written to the user's Mailbox but the message remains, also, in the 
queue of qmail (deferral: Segmentation_fault/) and at the second attempt 
is delivered fine.

If disable ACL (acl and imap_acl from mail_plugins) in dovecot.conf 
"Segmentation fault" go away. Moreover, without ACL at the first 
delivery folders like Sent, Drafts, Trash, Spam appear immediately.

An example,

new user:

root at demo-vpop ~ # tree 
/home/vpopmail/domains/qboxdns.it/cecchi2/Maildir/ -a
/home/vpopmail/domains/qboxdns.it/cecchi2/Maildir/
??? cur
??? maildirsize
??? new
??? tmp

root at demo-vpop ~ # cat testmail.txt | 
/usr/local/dovecot-2.1/libexec/dovecot/deliver -d cecchi2 at qboxdns.it
Segmentation fault

root at demo-vpop ~ # echo $?
139

gdb backtrace would be very helpful in figuring out the problem:
http://dovecot.org/bugreport.html

I see the same crashes on FreeBSD. Turning off ACL makes the crashes
disappear.

I'm getting a different backtrace though and it doesn't seem to be
related to ACL:

Also, can you reproduce the crash always by running "doveadm quota recalc
-u user at domain"?

If first add a news user, than run quota recalc and after deliver the 
first message "deliver" not crash:

# vpopmail/bin/vadduser test10 at qboxdns.it
# doveadm quota recalc -u test110 at qboxdns.it
# cat /root/testmail.txt | 
/usr/local/dovecot-2.1/libexec/dovecot/deliver -d test10 at qboxdns.it

When add a new user without quota recalc deliver crash:

# /home/vpopmail/bin/vadduser test12 at qboxdns.it
# cat /root/testmail.txt | 
/usr/local/dovecot-2.1/libexec/dovecot/deliver -d test12 at qboxdns.it
Segmentation fault (core dumped)
#

Hope this will useful
