My fault - changed this to double, and it worked.

Well, nearly - now it crashes when it reaches the edges:

$ ./separator -f test -i planar100k.graphml
terminate called after throwing an instance of 'boost::property_not_found'
   what():  Property not found: length.
Aborted

Why isn't
   dp.property("length", get(&EdgeProperties::length, g));
sufficient?
