PulseAudio doesn't have code that would generate an error message like that, so it looks like it's actually something else that is sending the error. Here the error sender is :1.35, which is not very useful, but if you get the dbus-monitor log again, you can check with d-feet what application is returning that error (in this case you'd check which application is :1.35, but that number will probably be different when you try again). -- Tanu
