It seems that bundled properties still don't work with subgraphs. I found a mention of the problem dating back to 2005 [1], a closed ticket for the issue [2] and another post [3], this time from 2008, with an ex tempore fix (which doesn't work for me). Could someone possibly account for that?

If I had to guess, I would say that there aren't very many people using subgraph so it's implementation hasn't evolved with the rest of the library. That's probably true of a lot of BGL code.

How quickly do you need a fix? I'm pretty busy for the next week of so, but I might be able to make some time this weekend.
