Unity.Activation interface is incompatible with PyGI

[Johannes H. Jensen]

Following the discussion on ayatana-dev: https://lists.launchpad.net/ayatana-dev/msg00148.html

The Unity.Activation interface is incompatible with PyGI because of the use of callbacks:

UnityActivationStatus activate (const gchar* uri, GAsyncReadyCallback _callback_, gpointer _user_data_);

Resulting in warnings and corrupt arguments when passed to python:

** (process:23642): WARNING **: You are trying to use an API which returns a callback.Callback returns can not be supported. Returning None instead.

The underlying problem seems to be that the interface is defined as async in the Vala code. As suggested by Mikkel in the mailing list, the method should be converted into a normal synchronous one, i.e.:

UnityActivationStatus activate (const gchar *uri);

This was fixed in the 4.0 series of libunity
