[Sugar-devel] [Sugar PATCH] sl#3169, sl#4226: Process the 'PropertiesChanged' signal-callback, only if the buddy has been added into the sugar-model.

[Ajay Garg]

There will be cases when we receive the "Properties" changed signal from telepathy for a particular "online" buddy; we then call the "__buddy_info_updated_cb" to process the signal, trying to update the properties.

However, if the buddy hasn't already been added to th sugar-model (via "AliasesChanged" signal ==> "__aliases_changed_cb" callback ==> "buddy-updated" signal ==> "__buddy_updated_cb" callback), there is no point processing the properties. At this point, it is ok letting go off the seemingly "missed" 'PropertiesChanged' signal, as the properties are added to the model, when the buddy is added to the model.

Next time onwards (after the buddy has been added into the model), any further 'PropertiesChanged' signal will be suitably processed.
