Same problem in Openbox Arch.

...For a solution.

[Andrew Williams (nikdoof)]

A second problem here is that the Arch Linux AUR package has a bit of a
stupid patch in it, where the package maintainer decided to rip out half of
the command code and replace it with a older version.

Using a fresh Git/Bzr copy with Arch may help your issues, but i've never
been able to get DBUS controlled startup/shutdown working under Arch due to
numerous smaller issues.

Adding the following to my .xinitrc fixed this issue for me:

exec ck-launch-session dbus-launch openbox-session

it seems to be important that ck-launch-session appears before dbus-launch, i.e. the order matters.

[Bernhard (b.a.koenig)]

Sorry, of course you don't need to add "openbox-session" if you are not running openbox. The crucial point seems to be that ck-launch-session appears before the dbus-launch.
