Muy ocasionalmente veo estas ventanas emergentes en informes de fallas en pantallas que usanNSFetchedResultsController, y no estoy seguro de cómo abordarlos. No creo que esté usando hilos en ningún lado, a menos queNSFetchedResults los usa internamente.

'NSInternalInconsistencyException', razón: 'la declaración aún está activa' es la explicación completa que obtengo.
