System Information
Operating system: Ubuntu 18.04.1 LTS
Graphics card: NVIDIA GT650M

Blender Version
Broken: version: 2.80 (sub 39), branch: blender2.7, commit date: 2019-01-01 15:44, hash: 4dd0a90f42, type: Release
Worked: 2.79b

Description:
Use spin tool to create curved mesh, then attempt to apply bevel. Bevel deforms incorrectly. Should bevel uniformly. When creating curve by other means (i.e. beveling or poly modeling) and applying bevel, functions as expected.

Reproduction:
Use default cube.
Place 3d cursor on a top edge (or anywhere thereabouts).
Select top face.
Use spin, 9 segmets, 90 degrees, remove extra verts.
Attempt to bevel curved edges produced by spin.
Edges bevel incorrectly.
(attempted this using both tris and ngons, same result.

Attached system info and blend file with example.bevel_bug.blend

The problem seems to be that the face orientation of the first created faces is wrong:

If you recalculate normals (so they are correct) the issue is solved.

I am sorry about posting in the wrong place. Cant remove it. But I put it here, where it (hopefully) belongs.

Not sure normals issue for spin is resolved. Please check.
I run into problems with spin, if I use spin on an edge which is not connected to any face.

Example file.
Spin_Normals_Bug.blend

How I reproduce …
Object "SpinDummy", I do a spin in Edit mode.
In Object mode, I set object shading to smooth shading. It reveals weird normals.
