Bug#740382: "Unable to bind socket for address" log messages when running under systemd

[Michael Biebl <biebl@debian.org>]

Package: cups-daemon
Version: 1.7.1-7
Severity: normal

When running under systemd, everytime I acces the web frontend or
restart the cups service, I get the following warnings in
/var/log/cups/error.log

E [28/Feb/2014:21:51:56 +0100] Unable to bind socket for address [v1.::1]:631 - Address already in use.
E [28/Feb/2014:21:51:56 +0100] Unable to bind socket for address 127.0.0.1:631 - Address already in use.

cups itself seems to work fine though. It's functional and I can access
the web frontend via http://localhost:631 and http://127.0.0.0.1:631
