[Debian-ha-maintainers] Bug#739873: ldirectord: Upgrade from sid: ldirectord fails to start: Error [8533] reading file /etc/ldirectord.cf at line $number: invalid address for virtual service

[Salvatore Bonaccorso]

Package: ldirectord
Version: 1:3.9.5+git+a626847-1
Severity: serious
Justification: fails to upgrade from previous version, does not start anymore

Hi Martin and HA team

Upgrading ldirectord from unstable to the version in experimental
(1:3.9.5+git+a626847-1) causes the package not to upgrade correctly
and ldirectord not starting anymore. I played around in a vm setup
with the configuration below to reproduce:

root at sid:~# service ldirectord status
[....] Running ldirectord: statusldirectord for /etc/ldirectord.cf is running with pid: 7537
root at sid:~# cat /etc/ldirectord.cf 
checktimeout=20
checkinterval=5
autoreload=yes
quiescent=no

# web service vip (http)
virtual=192.168.122.60:80
        real=192.168.122.55 gate 1 "/", "It works"
        real=192.168.122.56 gate 1 "/", "It works"
        service=http
        checkport=80
        protocol=tcp
        scheduler=wrr
        checktype=negotiate
        virtualhost="web-vip.local"
root at sid:~# apt-get -t experimental install ldirectord

With the above configuration now ldirectord does not start anymore.
