[Telepathy] Any way to provide email when using empathy with telepathy-gabble?

[Tim Garton]

When trying to connect to an Openfire Jabber server at work using
empathy (with telepathy-gabble underneath), I get this in the debug
output:

...
(telepathy-gabble:2658): gabble-DEBUG: connection_status_changed_cb:
adding callbacks
(telepathy-gabble:2658): gabble-DEBUG: connection_ssl_cb: called: The
certificate can not be trusted.
(telepathy-gabble:2658): gabble-DEBUG: connection_ssl_cb: called: The
server hostname doesn't match the one in the certificate.

(telepathy-gabble:2658): gabble-DEBUG: gabble_roster_close_all: closing channels
...

Is there any way to provide this?
