[Telepathy] A query regarding Presences-update

[Ajay Garg]

Thanks Xavier.

I would prefer keeping my current system (unless and until it is
_absolutely_ necessary).



As part of me making the last-sub-use-case work, I tried the following
signals as well ::

(i)
http://telepathy.freedesktop.org/spec/Channel_Interface_Group.html#Signal:HandleOwnersChangedDetailed

(ii)
http://telepathy.freedesktop.org/spec/Channel_Interface_Group.html#Signal:MembersChanged


But none of them hit the callback function (nor do I get any missing
function error), when the last-sub-use-case is hit.




So,

a)
Is that expected?

b)
If yes, I just wonder when (if ever) is the case when the above two signal
callbacks are hit, with a non-empty "Removed" list?


Thanks and Regards,
Ajay
