This is how I start dbus and empathy:

rdorsch@paddy:~/SW.nobackup/tapioca$ cat dbus-empathy
#!/bin/bash

PREFIX=/opt/gtalk
export PATH=$PREFIX/bin:$PATH
export LD_LIBRARY_PATH=$PREFIX/lib:$LD_LIBRARY_PATH
export XDG_DATA_DIRS=$PREFIX/share/:/usr/share/
export PYTHONPATH=$PREFIX/lib/python2.5/site-packages/:/usr/lib/python2.5/site-packages/

dbus-daemon --config-file=/etc/dbus-1/session-gtalk.conf --print-address | tee /tmp/dbus-gtalk-rd.log
rdorsch@paddy:~/SW.nobackup/tapioca$ cat empathyloc
#!/bin/bash
set -vxx
PREFIX=/opt/gtalk
export PATH=$PREFIX/bin:$PATH
export LD_LIBRARY_PATH=$PREFIX/lib:$LD_LIBRARY_PATH
export DBUS_SESSION_BUS_ADDRESS=$(head -n 1 /tmp/dbus-gtalk-rd.log)
echo DBUS_SESSION_BUS_ADDRESS: $DBUS_SESSION_BUS_ADDRESS
EMPATHY_DEBUG=all empathy $*rdorsch@paddy:~/SW.nobackup/tapioca$

dbus then starts mission-control (visible in the process list).


Empathy comes with these debug messages:
