Hi Stephan,
There was a bug in the subgraph implementation. The vertex_index property
map for the subgraph was returning the global indices instead of the local
indices, which caused havoc when it tried to use the global indices to
lookup in a local property map.
I've checked in the fix to subgraph.hpp into CVS.

Also note that the above should be "8" instead of "7".
