Hi,

I've now filed bug:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=435646

So hopefully the libc6 maintainer will take a look at this, and we can
get this patch included, which should make ipv6 behave essentially
invisbly unless it is configured.

Cheers,
                                        Andrew McMillan.
