I've seen a lot of questions involving splitting a line with the help of a point layer. I want to split a line in fractions of its length. For example, I have a line 400 meters long, I want to split it into four lines of 100 meters long each. There is the grass module v.split, but I get an error message when I start it from the qgis toolbox :
*"TypeError: object of type 'NoneType' has no len()"*
So I'm not sure, if I get it to work, if this would be a solution.
