dovecot - Jun 2014 - Problems with dsync and global acls

Hi all!

I have 2 servers running dsync tcp replication between them. After 
setting global ACLs to

* user=admin lrwstipekxa

on both hosts, I get the following errors during replication for every 
folder:

dsync-local(mwegrzynek): Error: Mailbox Trash: Failed to set attribute 
vendor/vendor.dovecot/pvt/acl/user=admin: Invalid right ''

This error first manifested in version 2.2.13, there were no such errors 
in 2.2.9 (stock Ubuntu 14.04) version.

Am I doing something wrong?

My configuration:

# 2.2.13.3 (6dab0352ccb3+): /etc/dovecot/dovecot.conf
