You could simply emit a dbus message to use libnotity stuff.

Open a terminal window and launch `dbus-monitor`: then run (on a second
terminal window/tab)

        notify-send -i dialog-error "Tracker was unable to connect to
        session bus" "This error usually means that the DBus service is
        not running. Please ensure buzz buzz buzz"
        
the output on (first) terminal could help you to build a dbus message to
have the same effect.

Of course, it works only if session bus is working and the connection
issue is trackerd-related...
