Comment 1 for bug 1068895

We will need a little more details, e.g. the exact igraph version, and also a file that reproduces this, because it works fine for me:

g <- graph.ring(10)
write.graph(g, "/tmp/g.gml", format="gml")
g2 <- read.graph("/tmp/g.gml", format="gml")

(Apart form some warnings about attributes.)
