Can you read the file via other R methods? 
Eg. can you run 

lines <- scan("ELX-context.gml", what=character(0))

If yes then could you please try it for other graphs as well?
The easiest to try would be 

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

If this works for you then could you please send me the graph you want to
read, or at least a minimal example graph which does not work 
for you.
