Error al iniciar Docky: Could not load type ‘SessionManager.SystemManager+IUPowerProxy’

Cuando actualicé de Fedora 22 a 23 tuve un problema al iniciar Docky, me daba el siguiente error:

[SystemService] Could not initialize needed dbus service: 'Could not load type 'SessionManager.SystemManager+IUPowerProxy' from assembly 'DBus.Proxies, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' because it is implements the inaccessible interface 'SessionManager.SystemManager+IUPower'.'

El problema con esto es que con Fedora 23 (no se con que otra distro pase también) Docky ya no puede manejar el “docklet” de “Manejo de sesión” (Session Manager), lo que nos permitía apagar o reinicar la máquina desde el dock, así que, por el momento, NO USES ESE DOCKLET.docky_funciona-no-usar-sesion-manager

Para corregir esto solo hay que eliminar los archivos de configuración de tu home y listo, en mi caso con las siguientes carpetas fue suficiente:

/home/tu_usuario/.cache/docky/
/home/tu_usuario/.local/share/docky/

docky_error_al_iniciarDespués inicias Docky y listo.
