System Information
Arch Linux, NVIDIA GeForce GTX 650 Ti

Blender Version
Broken: 2.77a abf6f08 makepkg

Short description of error
When creating an armature with deform properties, the Tail radius of the parent isn't propagated to the childrens' head radius and the other way around.

Video:

Exact steps for others to reproduce the error
"Based on a (as simple as possible) attached .blend file with minimum amount of steps" <- where do I attach files?

Create armature with 1 parent bone and 1 or more child bones.
Select the parent bone in edit mode.
On the bone tab under "Deform" change the tail radius
Select the child bone

> the head radius of the child bone is not equal to the tail radius of the parent bone.

Motivation
I fear that you will completely remove this feature, but I need it, as I have to create geometrical graph structures with sized nodes and blender is the only application I could think of which supports it. I use them to generate polygon geometry, but in a different way.

I can confirm that with 2.77a release, but not with current master, so would assume this has been fixed already, thanks for the report anyway.
Please check the latest build from our buildbot.
