title: GridView stops interacting after screen orientation changes
body: <p>I have activity with two tabs, which implements two similiar fragments, each fragment consist of <em>GridView</em>, loading items through <em>AsyncTask</em> and it works fine until screen orientatation changes... After that its only possible to click on action bar and switch between tabs, but <em>GridViews</em> completely stops interacting with user: scrolling, clicking or anything else. Nothing but standart <em>onSaveInstanceState(Bundle outState)</em> and <em>onRestoreInstanceState(Bundle savedInstanceState)</em> are implemented.</p>
  
  <p>I have no idea about this issue, need help.</p>
  
  <p><strong>UPD</strong>: Well, after each new orientation change one new instance of fragment appears.</p>
  
  <p><strong>UPD2</strong>: Deleted unneeded code.</p>
