Hello!

I am just trying to learn more about DBus and its python bindings. 
Unfortunately, I got stuck now. This is what I have so far:

The Server:

class HydraHALObject(dbus.service.Object):
    def __init__(self, bus_name, 
object_path='/de/lsh-marquartstein/Hydren/HydraHALObject'):
        dbus.service.Object.__init__(self, bus_name, object_path)
   
    @dbus.service.signal('de.lsh-marquartstein.Hydren.HydraHALIFace')
    def deviceAdded(self, deviceName, display):
        pass
       
    @dbus.service.signal('de.lsh-marquartstein.Hydren.HydraHALIFace')
    def deviceRemoved(self, deviceName, display):
        pass

bus = dbus.SystemBus()
busName = dbus.service.BusName('de.lsh-marquartstein.Hydren.HydraHAL', 
bus=bus)
hydraHALObject = HydraHALObject(busName)

gobject.MainLoop().run()


The Client:

bus = dbus.SystemBus()
hydraClientObj = 
self.dbus.get_object('de.lsh-marquartstein.Hydren.HydraHAL', 
'/de/lsh-marquartstein/Hydren/HydraHALObject')
hydraClientIFace = dbus.Interface(hydraClientObj, 
'de.lsh-marquartstein.Hydren.HydraHALIFace')
hydraClientIFace.connect_to_signal('deviceAdded', lambda udi, display: 
signalReceived('deviceAdded', udi, display))       
hydraClientIFace.connect_to_signal('deviceRemoved', lambda udi, display: 
signalReceived('deviceRemoved', udi, display))

gobject.MainLoop().run()

The server is started by root, that's why I added a system-local.conf 
file as I was suggested in a tutorial:

<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-BUS Bus Configuration 
1.0//EN"
 "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd">

<busconfig>
  <policy user="root">
    <allow own="de.lsh-marquartstein.Hydren.HydraHAL"/>
  </policy>
</busconfig>

Now I can start the server, but trying to launch the client as a normal 
user fails:

Introspect error: No reply within specified time
Traceback (most recent call last):
  File "ClientTest.py", line 13, in ?
    client = Client(debug=True)
  File "../Client.py", line 52, in __init__
    print 
hydraClientObj.Introspect(dbus_interface='org.freedesktop.DBus.Introspectable')

timeout)
  File "dbus_bindings.pyx", line 455, in 
dbus_bindings.Connection.send_with_reply_and_block
dbus_bindings.DBusException: No reply within specified time

I have done everything I can think of, but I did not help :-( Do you 
have any ideas?

Cheers,
Fabian
