System Information
OS X 10.9.4

Blender Version
Broken: 2.71 Hash: 9337574)

Short description of error
The Segments Value from the Bevel Tool panel doesn't do anything when beveling vertices of a plane.

Exact steps for others to reproduce the error

Launch blender
Delete the default cube
Add a plane
Enter Edit mode
Select all vertices
Bevel the vertices using Mesh -> Vertices -> Bevel

In the Bevel tool panel, tweek the Value for Segments

Actual result
The amount of Segments/Vertices doesn't change according to the entered value. The bevel transformation always results in only one segment, instead of the amount of segments entered in the Segments field.

Expected result
Additional Segments/Vertices should be created according to the value entered.

Howard, not sure whether this is a bug or design limitation?

It is partway between a bug and a design limitation. Vertex bevel was designed to work on vertices that have faces surrounding it on all sides. But the case of outside corners was made to work at some point and it is a bug that it doesn't pay attention to the number of segments in that case.

If you add a grid with 3x3 subdivisions and then vertex-bevel the center vertex, you will see that it does pay attention to the number of segments. But it uses straight lines to join the outsides, see:

I suspect that even if I fixed the outside corner vertex bevel to pay attention to multiple segments, it is probably not the effect you want. You probably want curved edges. This is where things start to get into a design limitation. It would mean treating bevels in a plane as a very special case, and I'm worried that as one transitions between "all in the same plane" to "just slightly non-planar" that the difference in treatment would be a jarring jump. The issues are similar to the problem that is making #39184 so hard to fix.

This was fixed a while ago, with commit dce59530d0 for part of another bug report, #43239
