keepalived: garp_master_delay not respected?

Hello,
I am trying to set up LVS director failover using keepalived's vrrp
function (debian stable version 1.1.12-1). In my backup director
keepalived.conf I put:
garp_master_delay 10
But in case of communication problems, in my syslog I get:
Apr 26 21:56:53 e49 Keepalived_vrrp: VRRP_Instance(VLAN1) Transition to

So it looks like gratuitous ARPs are sent twice: immediately when master
state is entered and again 5 seconds later.
What am I doing wrong?
Thanks,
