System Information
Windows 10, NVIDIA GTX970

Blender Version
Broken: 2.78c

I wanted to use the bevel tool with Profile factor 1.0 and even number of segments (4 on the pic) to add some edges to support my geometry, but the bevel tool affects the outer geometry and creates such "pompoms" in the corners. It works only for the orthogonal corners (like regular cube have), but even a simple box shape is affected by these strange "pompoms" in the corners. I think the outer geometry should always keep unchanged when Bevel Profile is set to 1.0.

@howardt are you around to fix these? If not I guess this can go to @campbellbarton.

This is a valid problem, but one that the current algorithm for handling profile=1 is not capable of solving. I need a new algorithm for that case, or more special cases. This is already a TODO on the general Bevel Improvements task, #48583, so I am closing this instance of the problem.
