Hmm. I don't think it's a problem with the python wrapping; I built and ran the
example on the wiki page you pointed out and get an empty graph when I revert
the vtkBoostPrimMinimumSpanningTree to the version in the repository. I am using
git VTK updated as of yesterday, Boost 1.42.0, and gcc 4.2.1. Perhaps it is a bug in
Boost or the VTK/Boost graph adaptors that has crept in at some point?
PS. I fixed a small filename inconsistency on the wiki page.
