Hi all,

Recently i've upgraded my cups version from 1.5.4 to 1.6.1.

With the previous version, no problems, bu now i can't modify the line "Listen localhost:631" of the "/etc/cups/cupsd.conf" file without obtaining the following error :
cupsd: client.c:757: avahi_client_get_host_name: Assertion `client' failed.

I'm using Archlinux ARM on a rapsberry pi.
