[Evolution] Offline Evolution switched online when NIC changes

[Steinar Bang <sb dod no>]

Hi!

After upgrading from Ubuntu Dapper to Ubuntu Feisty (a reinstall,
actually), the behaviour of Evolution (with exchange folders) changed:

An offline Evolution is switched online when the wired NIC is plugged
into a different network (or disconnected and reconnected in the same
network), or when switching from wired LAN to WLAN.

I reported it as a bug with Ubuntu
        https://bugs.launchpad.net/ubuntu/+source/evolution/+bug/120728

The person handling the bug thinks this is desirable, and expected,
behaviour of Evolution, which doesn't make sense to me.

So I'll ask here:
 1. is this expected behaviour of Evolution 2.10.1?
 2. if this is not expected behaviour, is this a known bug with
    upstream Evolution?
 3. if this is a known bug, is there a fix upstream?
 4. if this isn't a known bug, should I file it with the gnome
    bugzilla?  Does it belong on evolution or evolution-exchange?

I found this, which looks releated...?
