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) <a href="http://telepathy.freedesktop.org/spec/Channel_Interface_Group.html#Signal:HandleOwnersChangedDetailed">http://telepathy.freedesktop.org/spec/Channel_Interface_Group.html#Signal:HandleOwnersChangedDetailed</a> (ii) <a href="http://telepathy.freedesktop.org/spec/Channel_Interface_Group.html#Signal:MembersChanged">http://telepathy.freedesktop.org/spec/Channel_Interface_Group.html#Signal:MembersChanged</a> 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?
