This is happening because there's a line segment of zero length. I think what happened here is that you double-clicked while using the line tool.

I just got this error message while editing a map, googled it, and found this issue! I tried making the line again, being more careful at the end when I double clicked the end point to "finish" the line, and it saved ok.
