Please please cherry pick the patch from gnome bugzilla and apply it to vivid

This bug makes most IPv6 connections unusable without manual intervention (either setting the hop limit on each router that does not set that in RAs - most!) or manually changing the limit after every connection.

I wouldn't say it's critical (most of us still have IPv4 access too :), but it's definitely a High importance bug.
