I'm new to dbus, I've been using it for a little while consuming other peoples services and things like that.   Today I've started working on my own service, however I'm struggling a little to get it working. I've been using the following example code to try and get a service running on my system <A href="http://paste.lisp.org/display/45824">http://paste.lisp.org/display/45824</A> however when I attempt to run this python script I get the following error:     File "TestService.py", line 15, in ?     myservice = MyDBUSService()   File "TestService.py", line 7, in __init__     bus_name = dbus.service.BusName('org.frankhale.helloservice', bus=dbus.SessionBus())   File "/var/lib/python-support/python2.4/dbus/_dbus.py", line 217, in __new__     mainloop=mainloop)   File "/var/lib/python-support/python2.4/dbus/_dbus.py", line 106, in __new__     bus = BusConnection.__new__(subclass, bus_type, mainloop=mainloop)   File "/var/lib/python-support/python2.4/dbus/bus.py", line 125, in __new__     bus = cls._new_for_bus(address_or_type, mainloop=mainloop) dbus.exceptions.DBusException: org.freedesktop.DBus.Error.Spawn.ExecFailed: Failed to execute dbus-launch to autolaunch D-Bus session Does anyone have any ideas as to why I'm getting this error message?   Thanks guys, I appreciate any help you can offer.   Rob <hr />She said what?
