[Dovecot] problem with mail_full_filesystem_access = yes

[Ladislav Pašek]

Hello,

I have configured Dovecot 1.2.12 with Postfix 2.6.5 and everything is working fine. But tomorrow I wanted to run IMAP 
ALCs and from log I found that this plugin is conflicting with parameter mail_full_filesystem_access = yes in my config. 
But when I set  mail_full_filesystem_access = no it stops authorization for postfix with this message:

<pasek at valbek.cz>: Command died with signal 11: "/usr/libexec/dovecot/deliver"

Does anybody know what could be wrong in my config? I've spend a night with it but without success.
You can see my Dovecot here:

and Postfix here:
