When trying to connect to the session bus through my own code I get the following error:   dbus.exceptions.DBusException: org.freedesktop.DBus.Error.Spawn.ExecFailed: dbus-launch failed to autolaunch D-Bus session: Autolaunch error: X11 initialization failed.   I also find that whenever I'm trying to use a service which has been built to launch onto the session bus, it wont run and throws errors during its launch, a very similar error to above about X11 not working.   Can you guys give me a little help and advice into debugging what's causing this issue? I really don't know where to start looking. If you need any more information then ask away and I'll let you know as best I can.   Thanks,   Robert <hr />Messenger on the move. <a href='http://mobile.uk.msn.com/pc/messenger.aspx ' target='_new'>Text MSN to 63463 now!</a></body> </html>
