[Python-apps-team] Bug#913646: quodlibet 4.2.0-1 refuses to start

[Klaumi Klingsporn]

Package: quodlibet
Version: 4.2.0-1
Severity: important

Dear Maintainer,

after todays upgrade to 4.2.0 i testing quodlibet doesn't start any more. I only get an 
error-window, where I can ignore the errror or end he program. In both cases quodlibet 
doesn't show up. The error message in this window is:

Error: g-dbus-error-quark: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: Method "GrabMediaPlayerKeys" with signature "su" on interface "org.mate.SettingsDaemon.MediaKeys" doesn't exist
------
Traceback (most recent call last):

  File "/usr/bin/quodlibet", line 15, in <module>
    sys.exit(main())

  File "/usr/lib/python3/dist-packages/quodlibet/main.py", line 162, in main
    mmkeys_handler.start()

  File "/usr/lib/python3/dist-packages/quodlibet/mmkeys/__init__.py", line 77, in start
    self._backend.grab()

  File "/usr/lib/python3/dist-packages/quodlibet/mmkeys/gnome.py", line 72, in grab
    iface.GrabMediaPlayerKeys('(su)', self.__name, self.__grab_time)

  File "/usr/lib/python3/dist-packages/gi/overrides/Gio.py", line 295, in __call__
    None)

gi.repository.GLib.GError: g-dbus-error-quark: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: Method "GrabMediaPlayerKeys" with signature "su" on interface "org.mate.SettingsDaemon.MediaKeys" doesn't exist
 (19)

This makes the program unusable.
