Error setting status to empathy with dbus

I'm getting error when I try setting status to empathy with dbus using python, this is the code I've got from different sources

## getting status from clementine music player

import dbus

# Clementine lives on the Session bus
session_bus = dbus.SessionBus()

# Get Clementine's player object, and then get an interface from that object,
# otherwise we'd have to type out the full interface name on every method call.
player = session_bus.get_object('org.mpris.clementine', '/Player')
iface = dbus.Interface(player, dbus_interface='org.freedesktop.MediaPlayer')

# Call a method on the interface
metadata = iface.GetMetadata()
print metadata["title"]+' - '+metadata["artist"]
status = metadata["title"]+' - '+metadata["artist"]

when I run this script, I get the following error.

phanindra@phanindra:~$ python clementine.py 
onelove - Blue

(clementine.py:6142): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",
onelove - Blue is not supported by /org/freedesktop/Telepathy/Account/gabble/jabber/abcd_40gmail_2ecom0

I did something wrong? or the functions are deprecated?

Try this to update the status of Empathy with the current track playing in Clementine:

import dbus
session_bus = dbus.SessionBus()
player = session_bus.get_object('org.mpris.clementine', '/Player')
iface = dbus.Interface(player, dbus_interface='org.freedesktop.MediaPlayer')
metadata = iface.GetMetadata()
status = "♫ ".decode('utf8')+metadata["title"]+' - '+metadata["album"]+" ♫".decode('utf8')
print status
from gi.repository import TelepathyGLib as Tp
from gi.repository import GObject
loop = GObject.MainLoop()
am = Tp.AccountManager.dup()
am.prepare_async(None, lambda *args: loop.quit(), None)
loop.run()
am.set_all_requested_presences(Tp.ConnectionPresenceType.AVAILABLE,
'available', status)

Thank you for updating the Format in my original post ! - Harsha

Here is the API specification for the SimplePresence API's SetPresence call: http://telepathy.freedesktop.org/spec/Connection_Interface_Simple_Presence.html#Method:SetPresence

I think the problem is that you're trying to set the presence to an invalid status - you are only allow to set the status to one which the connection manager recognises - e.g. Available. You can set whatever you like for the message.

So your code should read something like:

simple_presence.SetPresence("Available", status)
