socket unit file

I'm trying to run saned via systemd socket activation on Debian jessie.

When I contact the scanner server from a remote system, systemd starts saned
correctly. However, saned thinks it is being started for localhost

systemd[1]: Starting Scanner Service (192.168.220.17:57533)
systemd[1]: Started Scanner Service (192.168.220.17:57533)
saned[607]: saned (AF-indep+IPv6) from sane-backends 1.0.24
saned[607]: check_host: access by remote host: localhost
saned[607]: init: access by host localhost denied
saned[607]: saned exiting

If I add localhost to the allowed hosts (saned.conf) I get the following error

systemd[1]: Starting Scanner Service (192.168.220.17:57533)...
systemd[1]: Started Scanner Service (192.168.220.17:57533).
saned[788]: saned (AF-indep+IPv6) from sane-backends 1.0.24 starting up
saned[788]: check_host: access by remote host: localhost
saned[788]: init: bad status=22 or procnum=-1225192048
saned[788]: saned exiting

When I use xinetd to start saned in the same setup, everything works as
expected.

I have reported a bug to the sane bug tracker

Somebody is experiencing the same problem with RedHat (I'm on Debian)
