Recientemente he descargado cm 13 y lo he flasheado en el Nexus 4. Desde entonces ninguna de mis aplicaciones puede descargar ningún archivo. Sin embargo, las aplicaciones de Google pueden hacerlo.
He intentado capturar la información de depuración pertinente de adb:

Edición: Problemas similares (prácticamente los mismos errores) existen en la última instantánea de CM 12.1 y en Slimkat (builds 4.4). En cuanto a la build slimkat, se ha utilizado durante más de un año sin ningún problema. Ahora sucede de la nada.
