arrowhead plugin problem

[denzjos]

@Ottia Tuota : No problem with the slice plugin. I've tried to reconstruct the problem. Because I had a few paths on my drawing I was working on, I must have pointed in the script menu to the circle instead of chosing the line (path) when I used 'slice path by lines'. Then the result is not ok and that is normal because I pointed to the wrong path in the script menu. Anyway, fine script !
