segfault on g.shortest_path_tree() in graph.c, line 355

[msoulier]

Rebasing to the latest graphserver code has been very bumpy. I am at commit

    Merge branch 'master' of git@github.com:bmander/graphserver

And now when I load a graphdb and try to find the shortest_path_tree, I get this segfault
