Bug#558125: - Caches the decision to use ipv6 over network topology changes

Tue Dec 14 10:07:18 UTC 2010

Package: epiphany-browser
Version: 2.30.6-1
Severity: normal
Tags: ipv6

I can still reproduce this problem with the lastest version. I'm using a
sixxs AYIYA tunnel. If you think it might be related I can also test with
native IPv6.

Steps to reproduce:

$ sudo /etc/init.d/aiccu start # start sixxs tunnel
$ ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

# now reload http://www.kame.net in epiphany. The result is an error page with:
# Unable to load page
#
# Problem occurred while loading the URL http://www.kame.net/
# 
# Cannot connect to destination

# if I restart the IPv6 connection I'm able to connect to the site again. If I kill epiphany 
# and restart it without IPv6 enabled I'm able to connect to http://www.kame.net and see the 
# IPv4 version (no dancing turtle).

Please tell me if you need more information or any help in debuging this.
