I see. I tried this on various graphs, and it indeed fails if you have loop edges in the graph. You can check for this with any(is.loop(net)) and remove them with simplify(). I remember fixing this issue with loop edges some time ago, it seems that it crept back. I cannot make walktrap to segfault, but it gives an error message about isolated vertices. This was already fixed in our development version. Did you get this error message as well?
