[Dovecot] Segmentation fault in doveadm with lib01_acl_plugin.so

Sat, 13 Oct 2012 01:16:52 -0700 

Hi,

I'm running dovecot 2.1.10 on Debian 6.
When I run "doveadm expunge -A mailbox Trash savedbefore 30d" it crash with "Segmentation fault"
[15022673.496902] doveadm[13072]: segfault at 8 ip 00007f4b7041f551 sp 00007fffdab4f8c0 error 4 in lib01_acl_plugin.so[7f4b70415000+10000] 

If I add -D to doveadm I can see this:

Segmentation fault
If I disable "acl" plugin in dovecot all works fine. I think that this problem is connected with "Dovecot deliver Segmentation fault when arrive the first message" http://www.dovecot.org/list/dovecot/2012-September/068343.html that I'm still experiencing. 

How can get core dumps from "doveadm"?

This is my dovecot config with acl enabled:
