Description
I have a plugin that runs the following code
layer = self.iface.activeLayer()
director = QgsLineVectorLayerDirector( layer, -1, '', '', '', 3 )
properter = QgsDistanceArcProperter()
director.addProperter( properter )
builder = QgsGraphBuilder( layer.crs() )
tiedPoints = director.makeGraph( builder, [] )
#graph = builder.graph()
#vn = graph.vertexCount()
#print(u"the graph has"+str(vn)+u" points")
When the function makeGraph is called then the qgis crashes
