Comment 8 for bug 1240455

a stroke width of "1" is interpreted according to the viewbox. if you set units to 'meters' it means 1meter stroke width.
the problem is (i think) that many extensions simply create an object with an arbitrary stroke width, not considering the document units.
So yes indeed, a bug, needs to be fixed, probably pretty easy to fix. simply convert the stroke width by calling "self.unittouu()" in the python script
