Hi all,
Might be something really stupid but I cant think of a problem. (maybe
its my limited experience with BGL common pitfalls)

        for (boost::tie(vi, vi_end) = boost::vertices(m_ugraph); vi !=
vi_end; ++vi) {
            depth += distances[*vi];
.....

path to:51886 distance to that node: 16.2 current total: 437998
path to:51887 distance to that node: 16.3 current total: 438014
path to:51888 distance to that node: 16.2 current total: 438031
path to:51889 distance to that node: 16.2 current total: 438047
path to:51890 distance to that node: 16.1 current total: 438063
path to:51891 distance to that node: 16.2 current total: 438079
path to:51892 distance to that node: 1.79769e+308 current total: 1.79769e+308
path to:51893 distance to that node: 16.3 current total: 1.79769e+308
path to:51894 distance to that node: 13.8 current total: 1.79769e+308
path to:51895 distance to that node: 13.9 current total: 1.79769e+308

I have checked my weights:

    if(edge_w<=0.0) edge_w = 0.1;
    if(edge_w >2.0) edge_w = 2.0;
    if( !(std::isnan(edge_w)) ) edge_w = 0.1;
    if( !(std::isfinite(edge_w)) ) edge_w = 0.1;

boost::dijkstra_shortest_paths(m_ugraph, *vertex_iterator_begin,
boost::distance_map(distanceMap));

typedef double Weight;
typedef boost::property<boost::edge_weight_t, double> EdgeWeightProperty;
typedef boost::adjacency_list<boost::vecS, boost::vecS,
boost::undirectedS, VertexProperties, EdgeWeightProperty> unGraph;

Any ideas?
Thanks a lot
