Short description of error
Simplify Curves (release/scripts/addons/curve_simplify.py) is a nice addon that comes in handy for example when you want to simplify a 3D Curve that you generated from a Grease Pencil curve. However, it seems to fail to assign the correct curve dimensions. After using the Simplify Curve operator on a curve, it first looks correct, but once you go into edit mode it jumps to a different location and shape. I think it is because the addon doesn't make the curve a 3D curve, but keeps it as a 2D Shape. When I make it a 3D Shape before going into edit mode it works just fine. I have a patch for the addon which seems to fix it, because this seems to be the intended behavior.

Exact steps for others to reproduce the error
Open the attached blendfile. There is a curve which was generated by converting a grease pencil stroke to a curve and after that running the Simplify Curves addon. It seems to be a 3dimenional object, even though the curve data shows it is a 2D shape. Now press Tab. The curve becomes a flat shape. If you undo that, make the curve a 3D shape and hit Tab again, it works fine.
