title: NSInternalInconsistencyException: no section at index 4
body: <p>Hi I have a simple database app on the iPhone that uses core data. I was just looking at some Flurry exception reports and I'm seeing the following error:</p>
  
  <p>NSInternalInconsistencyException: no section at index 4</p>
  
  <p>The number varies in the reports, but it is always the same message. Any idea on what this means and where to start my debugging efforts?</p>
