title: finditem() doesn't find menu, stuck with NullPointerException
body: <p>I'm stuck while changing some properties on my options menu at <code>onCreateOptionsMenu()</code>. It seems like findItem() returns null, even though I'm pretty sure that the reference to the menu item is correct. My code looks as follows:</p>
  
  <pre><code>    @Override
      public boolean onCreateOptionsMenu(Menu menu) {
          getMenuInflater().inflate(R.menu.activity_profile, menu);
          MenuItem leftie = menu.findItem(R.id.menu_profile);
          leftie.setIcon(R.drawable.ic_menu_mapmode);
          leftie.setTitle(R.string.back_map);
          leftie.setIntent(authIntent);
  
          return true;
      }
  </code></pre>
  
  <p>I really don't know what can be wrong there. Thanks in advance :)</p>
  
  <p>EDIT: I forgot to include the actual problem.</p>
