[Telepathy] A query regarding Presences-update

[Xavier Claessens]

Your packages are completely outdated. You need at least tp-salut 0.7.2.

Again you should not use dbus directly. If your app is written in 
python, please use telepathy-glib's python binding. see for example:

http://cgit.freedesktop.org/telepathy/telepathy-glib/tree/examples/client/python/contact-list.py

Regards,
Xavier Claessens
