Short description of error
I found some issues when I use BevelVertexTool (Ctrl+Shift+B hotkey).

Bevel PolyLine does not add segments. Even if i add 8 segments - there will be only one segment beveled. Here is video test: http://youtu.be/gNbdKG3bmX4
Bevel with many segments does not make rounded corners. Here is My video test: http://youtu.be/j-J-p2etHZQ

Here testing file: temp.blend

Exact steps for others to reproduce the error
Select and use Ctrl+Shift+B.

With respect to #1, yes that is a bug. I will attempt a fix.
With respect to #2, it is not obvious to me that those edges should be curved, or if so, which way they should be curved. I guess the grease pencil lines in the video are meant to show how you thought they should be curved but I was surprised - I actually thought you were going to say you wanted the curves to go the other way (curving into the interior of the cube faces. I think this is a case where there is no obviously correct answer. Often this means a case where a control needs to be added to give the artist a choice. I will consider this, though there are those who argue too many controls is confusing.

Hello @howardt .

About #2 Here is i try to explain how it should go:

Most 3d packages do rounding for vertices too.

OK Paul. I still contend that it is up for debate whether or not that is the "obviously correct" behavior. Do other 3d packages agree that that is the right thing to do? Anyway, I will probably try to program it up (it kind of goes with what I suspect you want for #1 anyway), and see what people think.

No problem! I just point that Edges are beveled smoothly. But points not.

Thanks for the development.

I fixed the bug reported in part one of this report, with commit dce59530d0

Howardt could this be also implemented into the bevel-modifier?
For a lot of cases it would be extreme useful. Imagine a non-destructive bevel modifier in conjunction with a solidify or a screw modifier...

thanks! #1 is super useful, but a bit hidden... when working with wire edges shouldn't bevel mode switch to only vertices..?
the F6 workflow feels weird here, you bevel but don't see anything, then use F6 to use 'vertex only' and it works, but it won't remember the setting later

totally unrelated, but having this also for bezier curves would be so cool

After some consultation with others, the consensus is that the current behavior in the video for report 2 is not a bug, and while it could be made an option to do as you want, it should not be the default. So I'm closing this bug for now, and will keep in mind that perhaps it could be an option in the future (though we can't keep adding more and more options to bevel). The first half of the bug was fixed a while ago, so calling this 'Resolved'.
