Comment 18 for bug 453099

I figured out what the problem is. I suddenly had a bright moment and remembered me finding dhcp6 settings last week that seemed wrong. They were set to "Ignore", while this is not the behavior i want, since I want NM to acquire dhcp6 addresses when available. Therefor i set it to "Automatic" on all networks i have in my list.
However, this seems to break ipv4 as well. When no dhcp6 address can be acquired, NM just disconnects. Although this is not related to the new package, as the title of this bug report implies, this is still a bug! I expect NM to just leave the network connected when it finds an ipv4 address and no ipv6, no matter what the setting for ipv6 is, since it has network connectivity. Disconnecting a working ipv4 is always wrong. I worked around the problem by setting ipv6 back to "Ignore" for now.
