Dbus-plugin does not work right.

[moma]

Totem's DBus-plugin may have a bug. I try to control the Totem-player from Audio-Recorder. Audio-recorder does see the player on the DBus but Totem does not reply requests.

This same bug was reported last year too. And year before. Now this annoying bug is back!
What the H* are they doing?

I run totem v3.16.2 on Ubuntu 15.10 (test).
$ totem --version
totem 3.16.2
--------

Totem fails to return "PlaybackStatus". Run the following dbus-send command in a terminal window. It is a long one-line command:

$ dbus-send --print-reply --session --dest=org.mpris.MediaPlayer2.totem /org/mpris/MediaPlayer2 org.freedesktop.DBus.Properties.Get string:'org.mpris.MediaPlayer2.Player' string:'PlaybackStatus'

Error org.freedesktop.DBus.Python.AttributeError: Traceback (most recent call last):

    return self.GetAll (interface_name)[property_name]

Totem fails to return "Metadata". Run the following dbus-send command in a terminal window. It is a long one-line command:

$ dbus-send --print-reply --session --dest=org.mpris.MediaPlayer2.rhythmbox /org/mpris/MediaPlayer2 org.freedesktop.DBus.Properties.Get string:'org.mpris.MediaPlayer2.Player' string:'Metadata'

Good samples:
Here are correct replies from the RhythmBox player:

Get PlaybackStatus from RhythmBox:

$ dbus-send --print-reply --session --dest=org.mpris.MediaPlayer2.rhythmbox /org/mpris/MediaPlayer2 org.freedesktop.DBus.Properties.Get string:'org.mpris.MediaPlayer2.Player' string:'PlaybackStatus'

method return time=1441188372.041001 sender=:1.146 -> destination=:1.149 serial=194 reply_serial=2
   variant string "Playing"
-----------------

And get Metadata from RhytmBox:

$ dbus-send --print-reply --session --dest=org.mpris.MediaPlayer2.rhythmbox /org/mpris/MediaPlayer2 org.freedesktop.DBus.Properties.Get string:'org.mpris.MediaPlayer2.Player' string:'Metadata'

method return time=1441188535.630312 sender=:1.146 -> destination=:1.161 serial=226 reply_serial=2
   variant array [
         dict entry(
            string "mpris:trackid"
            variant string "/org/mpris/MediaPlayer2/Track/2"
         )
         dict entry(
            string "xesam:url"
            variant string "http://ubuntu.hbr1.com:19800/tronic.ogg"
         )
         dict entry(
            string "xesam:title"
            variant string "After Midnight Dejavu (2006)"
         )
         dict entry(
            string "xesam:genre"
            variant array [
                  string "House"
               ]
         )
         dict entry(
            string "rhythmbox:streamTitle"
            variant string "HBR1.com - Tronic Lounge"
         )

....

BTW: I can see in the Audio-recorder (when debugging) that Totems sends some DBus-messages repeatedly. Audio-recorder gets mad by receiving 20 STOP, START, PAUSE, START, STOP, PAUSE, STOP... messages. I programmed a special workaround for Totem in Audio-Recorder.
