I accidentlly kill dbus daemon. IT rebooted and know everything wokr

One more question.
Is it possible to execute script via dbus-script on headphone button press?

Now I use python script to pause kagu when button press.
I have to start it from xterm each time when I start kagu.
Will be nice if need only start BT on IT and nothing more

#!/usr/bin/env python2.5

from dbus.mainloop.glib import DBusGMainLoop
DBusGMainLoop(set_as_default=True)

import dbus
import gobject
import os

dbus_loop = gobject.MainLoop()
bus = dbus.SessionBus()

def on_button_pressed (sender=None):
os.system('echo pause > /home/user/.kagu/fifo')


headset = bus.get_object('com.nokia.osso_hp_ls_controller', '/com/nokia/osso_hp_ls_controller')
headset_iface = dbus.Interface(headset, dbus_interface='com.nokia.osso_hp_ls_controller.he adset')
headset_iface.connect_to_signal('button_pressed', on_button_pressed, sender_keyword='sender')

dbus_loop.run()
