[igraph] Cannot read edgelist, File operation error

[Sam Steingold]

I get this error:
Error in read.graph.ncol(file, ...) : 
  At rinterface.c:4220 : Cannot read edgelist, File operation error
when I do read.graph("foo",format="ncol")
file.info reports that the file exists (but is rather large: 136,139,840
bytes, 3,374,442 edges, 6,960 vertices).
