This is only on my laptop, not on my server (also on feisty)
Both apt-get dist-upgraded from edgy eft as it happens.
So - a hosts file entry for ip6-localhost exists.
suresh@etherkiller 10:02:05 <~> $ grep ip6-localhost /etc/hosts
::1 ip6-localhost ip6-loopback v6.example.com
The localhost interface has ::1 (ipv6 localhost) bound to it
suresh@etherkiller 10:02:08 <~> $ ifconfig lo
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host

ssh and telnet to services on ip6-localhost dont work.
suresh@etherkiller 10:02:11 <~> $ ssh suresh@ip6-localhost
ssh: ip6-localhost: Name or service not known
While I can ssh just fine to ::1
suresh@etherkiller 10:02:34 <~> $ ssh suresh@::1

Are you sure you want to continue connecting (yes/no)? yes

Funnily enough ping6 to that same hostname works
suresh@etherkiller 10:02:27 <~> $ ping6 ip6-localhost
PING ip6-localhost(ip6-localhost) 56 data bytes

This is insane.. worked just fine on edgy and on feisty beta.
