merge paths on gives syntax error

[Eelco Nieuwstad]

Hi,

I am running the default Bird install (1.5.0-4build1) from Ubuntu 16.0.4 
and when I enable merge paths on the kernel protocol bird refuses to 
start because of a syntax error. This is the very default config I use. 
Do I miss something obvious?

log syslog { info, remote, warning, error, auth, fatal, bug };
router id 172.16.1.252;

# The Kernel protocol is not a real routing protocol. Instead of 
communicating
# with other routers in the network, it performs synchronization of BIRD's
# routing tables with the OS kernel.
protocol kernel {
        import none;
        merge paths on;
        export all;
}
protocol bgp {
  local as 65000;
  neighbor 172.16.3.2 as 65000;
}

protocol device {
        scan time 60;
}
