title: Application Icon Showing Default, not IconSet
body: <p>I have an app with two targets just about ready to ship but I still see the default app icon with the paper, pencil, etc. on the dock and in the main window when I select the app under Products.</p>
  
  <p>I have an icon.iconset folder with 16, 32, 128, 256, 512, and 1024, all following the icon_XxX and icon_XxX@2x naming; under Products in XCode I see my 16x16 icon.  Under the targets' summary tab, show-in-finder shows that the iconset folder is indeed the app icon setting, as do the plist files (sans iconset extension).  All appears to be well, yet I'm still seeing the default icon in the doc.  I'm using 4.5 but I had the same problem in 4.4.1.  Icons are pngs.</p>
  
  <p>Any ideas?  Thanks in advance.   </p>
