[Telepathy] Lost Empathy notifications on Gnome 3.4

[Pedro Francisco]

Hello!
On Gnome 3.4, I've this:

$ grep JS .xsession-errors
    JS ERROR: !!!   Exception was: Error: Error invoking
TelepathyGLib.ack_all_pending_messages_finish: invalid message id 2
    JS ERROR: !!!     lineNumber = '0'
    JS ERROR: !!!     fileName = '"gjs_throw"'
    JS ERROR: !!!     stack = '"("Error invoking
TelepathyGLib.ack_all_pending_messages_finish: invalid message id
2")@gjs_throw:0
    JS ERROR: !!!     message = '"Error invoking
TelepathyGLib.ack_all_pending_messages_finish: invalid message id 2"'
    JS ERROR: !!!   Exception was: Error: Error invoking
TelepathyGLib.ack_all_pending_messages_finish: invalid message id 2
    JS ERROR: !!!     lineNumber = '0'
    JS ERROR: !!!     fileName = '"gjs_throw"'
    JS ERROR: !!!     stack = '"("Error invoking

    JS ERROR: !!!     message = '"Error invoking
TelepathyGLib.ack_all_pending_messages_finish: invalid message id 2"'
    JS ERROR: !!!   Exception was: Error: Error invoking
TelepathyGLib.ack_all_pending_messages_finish: invalid message id 3
    JS ERROR: !!!     lineNumber = '0'
    JS ERROR: !!!     fileName = '"gjs_throw"'
    JS ERROR: !!!     stack = '"("Error invoking
TelepathyGLib.ack_all_pending_messages_finish: invalid message id
3")@gjs_throw:0
    JS ERROR: !!!     message = '"Error invoking

I also lost a notification icon for unread messages, so I'm guessing
it is related?

P.S.: can't trigger it at will; also, I had a disconnect while/before
this happened, so may or not be related: Gabble has the tendency of
crashing with SIGTRAP when I lose the connection (
