I see what's going on. The documentation says that weight_map is  
optional (defaults to all weights = 1.0), but the code didn't agree.  
I've just committed a fix to the SVN repository that makes weight_map  
optional for dijkstra_shortest_paths... your example code works fine  
for me, now.

Again, my apologies for the abysmal response time :(
