Hi Xavier.
I upgraded to a Fedora 17, and am using telepathy-salut 0.8.
As suggested by you, I am now able to get the initial list of contacts (at
startup) by using
http://telepathy.freedesktop.org/spec/Connection_Interface_Contact_List.html
Thanks.
However, my original issue still remains unsolved.
When a contact disconnects (from the telepathy network), the callback
function --- specified for the signal
http://telepathy.freedesktop.org/spec/Connection_Interface_Contact_List.html#Signal:ContactsChangedWithID---
is NOT hit.
Are you sure that this is intended to work (that is without using the
experimental, unstable
http://telepathy.freedesktop.org/spec/Connection_Interface_Keepalive.html) ?
Would be glad to hear back from you.
Thanks and Regards,
Ajay
