turtle serialization of same rdf:List in different triples as object fails

[WhiteGobo]

I have a list which i use in different triples:

@prefix ns1: <http://example.com/> .
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .

[] ns1:prop _:Ne7d .

[] ns1:prop _:Ne7d .

_:N849 rdf:first ns1:b ;
    rdf:rest () .

_:Ne7d rdf:first ns1:a ;
    rdf:rest _:N849 .

When using rapper, the list ist broken:

rapper -i turtle -o turtle test.ttl

@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix ns1: <http://example.com/> .

(ns1:a
    ns1:b
) .

[]
    ns1:prop _:Ne7d .

[]
    ns1:prop _:Ne7d .

Found this error during working with the raptor library. So the error should also exist, when using the serializer directly from raptor_new_serializer

Tested on archlinux. raptor version 2.0.16-6
