chrome extension blocking google.co.uk

I have a simple unpacked chrome extension loaded. All other extensions turned off.

manifest.js

{
  "manifest_version":2,
  "name":"Etc",
  "description":"Etc",
  "version":"1.0",
  "content_scripts": [{
      "matches" : ["*://*/*"],
      "js": ["contentscript.js"],
      "run_at":"document_end"
  }],
  "background": {
    "scripts": ["background.js"],
    "persistent": false
  },
  "permissions":[
    "tabs", 
    "*://*/*"
  ],
  "browser_action": {
    "default_title": "Idonethis", 
    "default_icon":"icon.png"
  }
}

The background.js

chrome.runtime.onMessage.addListener(
  function(request, sender, sendResponse) {
    if (request.greeting == "hello")
      sendResponse({farewell: "goodbye"});
});

The contentscript.js

chrome.runtime.sendMessage({greeting:"hello"}, function(response) {
  console.log(response.farewell);
});

On most domains such as www.bbc.co.uk the message passing works correctly and displays 

message contentscript.js:2

However on www.google.co.uk or uk.yahoo.com it does not pass a message, nor execute any contentscript.js as far as I can tell. Is this part of the security specification of chrome extensions?

EDIT This code has been fixed and can be viewed here https://github.com/lindaymacvean/test-chrome-ext

It's probably because of the match rule "matches" : ["*://*/"]. You need to change it to "matches" : ["*://*/*"] because currently it only matches tabs that have no path on them. E.g. http://example.com/ will match but http://example.co.uk/foo will not match.
