Empathy thinks a server certificate from www.EXAMPLE.com isn't from EXAMPLE.com

[Feathertail]

Binary package hint: empathy

PROBLEM

When I go to log into LiveJournal's XMPP server on Empathy, I get a dialogue that says:

"The identity provided by the chat server cannot be verified.
The hostname verified by the certificate doesn't match the server name.
Expected hostname: livejournal.com
Certificate hostname: www.livejournal.com"

This dialogue comes up every time I open Empathy or reconnect to the server, unless I tell it to ignore certificate errors in the advanced preferences under "Accounts."

HOW TO REPRODUCE

1. Sign up for a LiveJournal account.
2. Log into their XMPP server using Empathy. Instructions are available at http://www.livejournal.com/chat/

In light of the fact that Empathy's Accounts menu includes an option to ignore certificate errors, it seems likely that this error can be reproduced on other XMPP servers.

EXPECTED BEHAVIOR

Empathy will not throw up error messages that suggest that it lacks basic reading comprehension skills.

Empathy is completely right here. A certificate for www.example.com is not valid for example.com., the problem here probably lies in livejournal.com hands.

A better support for SSL certificate verification has been added in 2.9x/3.0 branch (allowing to add exceptions) but still empathy is right here to warn you about hostname/certificate CN mismatch.

I'm tempted to close this bug as invalid.

That's probably a good idea. >.> Sorry about that.
