@Eric
Interesting that it works in Python... I don't know what to think about that.

You're right about the points- I had just added them when doing the
standard (non vtkGraphLayoutView) pipeline and I forgot to remove them
when we switched back to this.

@Clinton
I applied your patch but now I don't even see the correct graphs
before it crashes - rather just a white window (and it still crashes).

Thanks,

David
