title: Webpart registration error in event log
body: <p>We created several custom web parts for SharePoint 2007. They work fine. However whenever they are loaded, we get an error in the event log saying:</p>
  
  <blockquote>
    <p>error initializing safe control - Assembly: ...</p>
  </blockquote>
  
  <p>The assembly actually loads fine. Additionally, it is correctly listed in the <code>web.config</code> and <code>GAC</code>.</p>
  
  <p>Any ideas about how to stop these (Phantom?) errors would be appreciated.
