[Bug 743523] [NEW] Empathy thinks a server certificate from www.EXAMPLE.com isn't from EXAMPLE.com

[Feathertail]

Public bug reported:

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.
