Comment 17 for bug 202540

(wipes egg off face) I did not test with enough parameter variations of Add Nodes. This new patch seems to handle every shape correctly (curves, straight, combo, compound and closed/open versions of all the above) with a range of parameter settings.

One thing - if you have a path with two points directly on top of each other, Add Nodes will happily add nodes 'between' them, resulting in a stack of nodes :) This seems to me to be the correct behavior, though I'm not sure it's particularly useful.
