title: Fabric Plugin: Archive Packaging Error: -6 Error re-signing the application for distribution
body: <p>When I try to upload a new build using the Fabric Plugin I get the following error:</p>
  
  <p><strong>Archive Packaging Error: -6</strong> 
  Error re-signing the application for distribution.</p>

  <p>It used to work until the last version of the app. And then for some reason it just stopped working. Here's what I've tried:</p>
  
  <ul>
  <li>Clean / Rebuild / Archive (many times)</li>
  <li>Uninstall / reinstall Fabric plugin</li>
  <li>Re-download provisioning profiles</li>
  <li>Change from automatic to manual signing</li>
  <li>Searching for missing code signing identity (> security find-identity -p codesigning)</li>
  </ul>
  
  <p>What's killing me is I can't figure out for the life of me where Fabric is pulling that codesign identity value (937558639C8878BB6E161112505FA2965804A6AE) from. It's not in the project as I've grepped for it. Could it be cached somewhere else?</p>
