Error con la propiedad synthesizeObjectProperties

[Fransiro]

El problema es la propiedad synthesizeObjectProperties cuando es false y la propiedad ignoreLiterals es false también no me genera el .dot.

Este es el archivo ttl que uso:
http://girtab.dia.fi.upm.es/files/stat1.ttl

Esta es la configuración que imprime:

{"equivalentElementList":[],"ignoreElementList":["http://www.w3.org/2000/01/rdf-schema#subClassOf"],"includeOnlyElementList":[],"keys":{"arrowColor":"blue","literalShape":"rectangle","individualShape":"rectangle","classShape":"rectangle","nodeNameMode":"localname","arrowhead":"normal","literalColor":"green","rankdir":"LR","classColor":"orange","arrowdir":"forward","ignoreRdfType":false,"ignoreLiterals":false,"individualColor":"yellow","imageSize":"1501","arrowtail":"normal","synthesizeObjectProperties":true},"specialElementsList":[]}
