Setting 'LCDServerHost' to 127.0.0.1 in the settings table fixes the problem. It looks like the localhost lookup is returning the ip6 localhost address 0:0:0:0:0:0:0:1 which is then causing the connection to fail.

The default hosts file in Ubuntu is :-

{{{
127.0.0.1	localhost
127.0.1.1	<this is set to the host name>

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
