I found this definition of viewBox: The *viewBox* attribute defines the position and dimension, in user space, > of an SVG viewport. > The value of the viewBox attribute is a list of four numbers: min-x, min-y > , width and height.

So it looks more like InkScape and the SVG import are both wrong. Perhaps the PDF is not simply a line drawing, i.e. the lines are actually thin filled rectangles rather than a line with stroke.
