I know what happened: the algorithm can only handle connected graphs,
and the graph that's being generated is disconnected. I had to grep
through the documentation page to find the (single!) place where it
said that a connected graph is required.
Anyway, I'm updating the documentation to be explicit about the
connectedness requirement, which will be checked by the algorithm (it
will return false for a disconnected graph or one with a negative
weight cycle). The changes should be in shortly...
