I have located the problem of specifying the scanner directly in the backend config.
kjotte@mystic:/tmp$ apt-get source sane-backends ... kjotte@mystic:/tmp/sane-backends-1.0.23/backend$ grep -n gethostbyname pixma* pixma_bjnp.c:1145: result = gethostbyname (hostname); This will need to be rewritten to use getaddrinfo().

We would prefer to use IPv6 wherever possible in our environment, so this is a blocker.
