Launch your shell with dbus-launch.   For example:

dbus-launch xterm

This starts a session bus and points an environment variable to it.  You
can then run your programs in that shell. 

Not all distros are starting session buses in their sessions yet.  Those
that don't you need to use the trick above.  In Fedora we use dbus-
launch to launch gnome-session so that the session bus is available to
the whole session.
