[Boost-users] BGL python bindings: write_graphviz never returns

Hi, I've recently run into a problem where I build a boost.graph in python and then call write_graphviz() which never returns. I haven't managed to generate a reproducible test case yet. All I can say is that the problem disappears if I remove all the edge and vertex properties. Has any one seen anything like this before? When I manage to make a small test case I shall post it. Best, John.
