The behaviour of the internal graph property maps changed exactly in
version 2.2.19. Here is the commit:

http://git.skewed.de/graph-tool/commit/?id=14b91f60ce6fcb4d834b85eee49408f7be50b0d7

In the current versions, the dictionary returns the map values, not the
property map object themselves, so that one does not need to keep
passing the graph object as key any longer, which was redundant.

Cheers,
Tiago
