--- Operating System, Graphics card ---

Tested on :
Windows 7
OSX Lion
Mint 14/15

CGs : GTX 560Ti

--- Blender version with error, and version that worked ---

Tested on 2.67b and 2.69RC3

--- Short description of error ---

Linking a skin modifier from an object to an other with CTRL+L>modifiers will copy the skin modifier but nothing happen (modifier doesn't work if not added manually for each object)

--- Steps for others to reproduce the error (preferably based on attached .blend file) ---

* Add cube.ONE
* Add a skin modifier to cube.ONE
* Add cube.TWO
* Select cube.TWO (first) and cube.ONE
* Copy modifiers (CTRL+L > modifiers)
Result : Skin modifier is copied on cube.TWO but doesnt seems to work

Thanks
