D-BUS upgrade

I had this error:
----------------------

GStreamer could not create the element: autoaudiosink. Please make sure that you have installed all necessary GStreamer plugins (e.g. OGG and MP3)

To fix it I ran this:
------------------------------

sudo pacman -S gstreamer0.10-good-plugins

but I got this as a warning during installation:
--------------------------------------------------------

(gconftool-2:6725): GConf-WARNING **: Client failed to connect to the D-BUS daemon:
/usr/bin/dbus-launch terminated abnormally with the following error: No protocol specified
Autolaunch error: X11 initialization failed.

which has been solved here https://bbs.archlinux.org/viewtopic.php?pid=1248143 but I can't upgrade dbus with pacman -U dbus
