I see a "solution" to this bug. In my opinion, if you need ipv6, your ISP will warn you, and you will know. So, the solution could be blacklisting ipv6 by default, and putting a checkbox in system/administration/network/general to enable it (the module can be loaded on the fly I suppose, so there would even be no need to reboot). I could be happy with enabling it by default, too, but with the same checkbox ready there. Current situation is just a mess where many users will try ubuntu from XP and notice that "internet is slow", and if we are lucky, they will look on the web and find an "evil command line" solution.
