title: xCode 5.1 CopyPNGFile Error
body: <p>Since I installed XCode 5.1 today I get a CopyPNGFile Error for every image that is located in a folder where I did not create a folder reference.</p>
  
  <p>So when I add a folder with images and create a folder reference for it and dont select the option "Create groups for any added folders" when importing then I dont get an error. And when I dont create a reference I get an error.</p>
  
  <p>I used Xcode 5.1 until Beta 5 and never encountered problems before in the beta period.</p>
  
  <p>In the build phases everything looks alright. No red marks.</p>
  
  <p>Does anybody else have this problem too and maybe know why?</p>
