Hmm.  Are you sure that the daemon is actually running?  My guess is
that the daemon died because of some weirdness in your session.conf (in
particular having two <listen> directives looks wrong).

For what it's worth, I don't use a custom .conf file.  Instead I do
debugging like this:

In one terminal, run:

DBUS_VERBOSE=1 dbus-daemon --session --print-address

That will print an address like this (along with other debug goo):


Then in another terminal, do:

export DBUS_SESSION_BUS_ADDRESS=unix:abstract=/tmp/dbus-hBeFb6bmsV

Now just run your test service:

./service # or whatever

In another terminal, I do the same export, then run the test clients.
