dovecot-lda crash after upgrade to 2.2.28

Tue Feb 28 11:16:49 UTC 2017

Hi!

I posted this problem few days ago in FreeBSD bugtracker
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=217364
So, the problem is in crash of dovecot-lda client while
local mailbox delivery with this message in log
> dovecot: lda(my at email): Panic: file mail-namespace.c: line 709 
> (mail_namespace_find): assertion failed: (ns != NULL)
My Dovecot config stills the same from previous 2.2.27 installation
to I believe that problem in new Dovecot code related namespace.
System:
