[pkg-wicd-maint] Bug#854176: wicd: Support IPv6-only networks

[Paul "LeoNerd" Evans]

Package: wicd
Version: 1.7.4+tb2-3
Severity: normal
Tags: ipv6

wicd gets upset on IPv6-only networks, on which no IPv4-talking DHCP
server exists to give an IPv4 address.

Such a network is run every year by FOSDEM, to let users test how well
their software works. Every year, we find many things that don't.

The specific failure mode is that the network layer correctly negotiates
IPv6 connectivity, and all networking seems to work just fine. However,
wicd does not believe it has been set up yet because it's still running
the "Obtaining IP addres..." spinner. After it gets bored waiting for
that 'v4 address, it decides the connection wasn't going to work and
tears it down again.

To solve this, it might be useful at first to make it a non-default
option; something like a ticky-box in network properties to select if
the network is 'v6-only

  [ ]  IPv6-only network

If such option were ticked, then wicd shouldn't bother awaiting an IPv4
address, but simply be happy when a 'v6 has appeared.
