nautilus-dropbox falla al iniciar con "pylinux import..

Sitema Operativo que uso: UbuntuStudio 13.10 X86

Si a alguien no le funciona el Dropbox (a mi me funcionó bien meses -desde que publicaron la ISO- y desde antes de ayer -2014-01-02- no me funcionaba, me pedía clave y nunca funcionaba), ponga en una terminal:

dropbox status

si le dice que no está corriendo (algo así como "dropbox doesn't runnig", ponga en la terminal esto:

dropbox start

y si le sale este error:

La solución es esta, ponga en el terminal (uno por uno):

sudo rm -rf /var/lib/dropbox/.dropbox-dist
dropbox start -i
