Python no puede acceder a Keychain cuando se ejecuta a través de SSH, ¿pero funciona desde una terminal local?

Utilizo Pushbullet CLI para enviar notificaciones Pushbullet desde la terminal. Funciona bien cuando lo ejecuto localmente, pero cuando hago SSH en la máquina donde está instalado e intento enviar una notificación, obtengo un seguimiento de Python:

% pb push test

Durante el manejo de la excepción anterior, ocurrió otra excepción:

Supongo que el problema es que la shell que obtengo al hacer SSH es diferente de una shell local, pero ¿cómo lo arreglo?
