I was in a coffee shop yesterday.
The wireless network they have uses some sort of captive portal to get access. When the system gets connected to such a network, *before* I log in in the captive portal, telepathy tries to connect my Google account to the XMPP server.
Apparently the auth client gets confused though, and I get a lot of dialogs asking me if I want to accept the certificate, which in this case is coming *from the captive portal*.

I think there are multiple bugs here:
- I should never get an auth client dialog for a certificate which doesn't come from the XMPP server itself
- After I dismiss the dialog (with Continue IIRC) I get it again and again after a bit, since obviously I am not really connected to any public network and connection keeps failing. It should not retry connection in a row like that though
- I think ideally I should never ever get an auth dialog like that at all for GOA accounts (it's OK to get it if I'm connecting to a home/local/LUG server, but never for Google or Windows Live)
