[SOLVED] Banshee could not start DBus, cli controls start new instance

I'm using systemd and when I run banshee it complains that DBus could not be started (which I thought already was with systemd). Banshee runs successfully, but as a result of this I can't use keyboard controls.

That is:

$ banshee --toggle-playing

starts a new instance of banshee.

Here is the output I get when running banshee:

$ banshee
[Warn  10:50:48.669] DBus support could not be started. Disabling for this session. - System.ArgumentNullException: Argument cannot be null.

Here are some other people who've had the same (or a similar) issue:

Edit: Solution
I was not loading my window manager with "exec dbus-launch <window manager>"

$ tail -1 .xmonad/startxmonad 
exec dbus-launch /usr/bin/xmonad

Thanks.

Re: [SOLVED] Banshee could not start DBus, cli controls start new instance

Systemd does not start a dbus-session (at least not automatically or by default).

What WM/DE are you using?  Do you launch your WM with "exec dbus-launch ..." or have dbus-launch otherwise run in your xinit/DE startup?

The threads you linked to suggest that dbus-launch solves the problem.  For some reason they were trying to run banshee only with dbus-launch, rather than there whole session.  Check a process monitor (pstree/htop/ps/top): you should see three dbus processes.
