title: Chrome extension icon not appearing?
body: <p>I'm trying to get an icon to appear for an extension at chrome://extensions/ page. My manifest is as follows:</p>
  
  <pre><code>{
    "name":"Hello World",
    "version" : "1.0",
    "description":"Hello World",
    "icons": {                   
      "19": "icon19.png",
      "38": "icon38.png",
      "48": "icon48.png",
      "128": "icon128.png"  
    },    
    "browser_action": {
      "default_icon": {                   
        "19": "icon19.png",
        "38": "icon38.png",
        "48": "icon48.png",
        "128": "icon128.png"        
      }
    },
    "manifest_version": 2
  }
  </code></pre>
  
  <p>As you can tell, I've tried putting icons all over.  They are all the corresponding size, but I simply cannot get an icon to appear in the extensions menu.  Thanks in advance.</p>
