title: Remaing keys in keychain access
body: <p>I recently revoked my certificate on apple.developer account. After that I downloaded the new one, and install it in Keychain Access. When I tried to build a app in Xcode 3.2.6 or 4.2, I was getting an error message explaining that I have two certificates with the same reference. So I deleted the one I had revoked. Then the build did not encounter any problem.</p>
  
  <p>But each time I restart my computer, the deleted key appears again and I still need to delete it before to build.</p>
  
  <p>Does someone knows how to resolve this problem ?</p>
