title: Cursor Loader observer already registered error
body: <p>I have an <code>AutoCompleteTextView</code> in my application, and I am loading the data with <code>CursorLoader</code>. Apparently there is some problem with the loading of data using this approach, because from time to time I keep getting this error:</p>
  
  <pre><code>07-01 11:17:49.209: E/AndroidRuntime(20758): java.lang.IllegalStateException: Observer
  android.widget.CursorAdapter$ChangeObserver@422dd8b8 is already registered.
  </code></pre>
  
  <p>Did anyone have this kind of problem?</p>
