Yes, I see the same issue, even when using OverlapRemovalAlgorithmType in XAML, as per the tutorial example.

Incidentally, my workaround for this was to wrap this assignment with a try...catch and ignore the exception.  So far, I've been able to get away with that, but I don't know what I'm missing out on algorithmically.  :)

With this issue, are you using the downloadable binaries of graph# or are have you compiled the latest src?

I downloaded from SVN yesterday and tried and got the same results.
