Ok I found out the problem meanwhile you were answering. I had 4 lines but three of them where very weird: 2 points, vertex to the same vertex -> a point, but stored as a line. I couldn't see it, beacuse it was superimposed on the major, single line. I think it was a problem with the original shapefile...
