Property maps do not automatically show up in the internal
dictionary. Here it should be simply:

    mylabel = g.new_vertex_property("string")
    for v in g.vertices():
       mylabel[v] = str(g.vp['labelv'][v])+" ("+str(g.vertex_index[v])+")"

or alternatively, you should store the property in the dictionary first:

    g.vp["mylabel"] = mylabel

Best,
Tiago
