 > The bug is still in issue in all versions.

 This should be fixed in all versions with r53738-40, but similar bugs may
 still exist in some modules.

 (well, I know it is the number of nodes you also get as output of v.build
 network) and what it is used for here, but it certainly is not related to
 the nodes (i.e. the schools) I added with the v.net command.

 These nodes are topological nodes as reported by v.build and not
 necessarily network nodes as added with v.net. What Vect_net_build_graph()
 does is going through all topological nodes and then looking if a network
 node (GV_POINT) exists at that topological node.

 looking.

 Sorry for interfering;)
