Well, to be honest, I have no idea, because we simply use the original implementation of Reichardt & Bornholdt for the spinglass clustering method. Probably the result is useless, and indeed we should add an explicit check in the C layer for negative or zero weights for the default implementation. (Although I suspect that zero weights should not cause a problem).
