System Information
OS: Ubuntu linux 14.04 LTS 64bit

Blender Version
Broken: 2.77 74e4066

Short description of error
When you duplicate an object with Alt-D it links the mesh data and all of it's properties. If you add a shape key, vertex color or uv map to one of them, it will be added to the other as well. But if you add a vertex group to one of the liked objects, it will not be added to the other.

Exact steps for others to reproduce the error
In the attached blend file there are two cubes, both with the same object data, but one has a vertex group and the other does not.

thanks for the report, but there is no bug here, vgroups are partly defined in mesh data, but also partly in Object data itself, this (unfortunate) design prevents what you describe above to work…
