Error al intentar abrir Emacs.app nuevo después de la actualización a Yosemite

Después de actualizar a Yosemite lo consigo cuando trato de lanzar una nueva aplicación Emacs desde la command-line. He pasado el día de ayer intentando descubrir cuál es el problema, así que hoy decidí preguntar aquí.

➜ ~ open -n -a Emacs LSOpenURLsWithRole() failed for the application /usr/local/Cellar/emacs/24.3/Emacs.app with error -10810. 

Editar: podría ser útil, información de /var/log/system.log:
