Comment 16 for bug 43464

I second Rob D's comment, I also don't get the "Error grabbing key" message.

Furthermore, I confirmed the keys are "grab-able" with the following test:
1. Open quodlibet
2. Try using multimedia keys to control quodlibet -- no effect
3. Without closing quodlibet, open Rhythmbox
4. Try using multimedia keys to control Rhythmbox -- works fine

The full output of quodlibet when run from the terminal is as follows (up-to-date Ubuntu Feisty Fawn system:)

fraser@ged:~$ quodlibet
Supported formats: mod, mp3, mp4, mpc, trueaudio, wav, wavpack, xiph
Loaded song library.

/usr/share/quodlibet/qltk/dbus_.py:11: DeprecationWarning: The dbus_bindings module is deprecated and will go away soon.

dbus-python 0.80 provides only a partial emulation of the old
dbus_bindings, which was never meant to be public API.

Most uses of dbus_bindings are applications catching the exception
dbus.dbus_bindings.DBusException. You should use dbus.DBusException
instead (this is compatible with all dbus-python versions since 0.40.2).

If you need additional public API, please contact the maintainers via
<email address hidden>.
