Short description of error

There seems to be an issue when converting grease pencil strokes to curves. My aim is to use a nurbs circle to be the "bevel object" to extrude along a path or bezier curve, using curve properties menu.

When I create a nurbs curve primitive (path or bezier) this works fine. However when I use a curve that has been converted from a grease pencil stroke, it doesn't work at all (referring to bevel object)

Infact, the actual converted curve seems to disappear in the viewport unless it is selected via outliner.

Exact steps for others to reproduce the error

Create a curve circle
Draw a grease pencil line (ctrl +D + right click drag)
Convert that grease stroke to a path or bezier
Access curve properties, and try to use circle as Bevel Object

File below contains two grease pencil convert curves (they fail), and one nurbs path (that works)

Yeah, seems like with first and last point of converted curve have their radius set to zero… Can be nice for hand-drawn strokes, but not good for poly- or single-lines.
