I have fixed the ~ issue in Rgraphviz devel. I have provided a couple of checks that catches trying to plot a graph with zero number of edges, but idoes not fix the issue of agreed(layout = TRUE) which is the default and which caused the segfault. Fixing this requires more tinkering due to the class hierarchy. Since I kind of want to fix the class hierarchy anyway in Rgraphviz, I have decided to postpone this.
I still believe that the file is somehow invalid because it is not being parsed by dot from Graphviz, so I consider this to be an igraph problem.
