Broken view of ActionBar after calling invalidateOptionsMenu, setSupportProgressBarVisibility and notifyDataSetChanged?

Question

Android

Noticed some unpleasant behavior in ActionbBar (ActionBarSherlock in particular). In the application, I use FEATURE_INDETERMINATE_PROGRESS which is shown when performing some actions. Also, when progress is shown, the action refresh should be hidden. To hide it, I have to call invalidateOptionsMenu, which, in turn, calls onPrepareOptionsMenu where I can already change the visibility

Override
public void onPrepareOptionsMenu(Menu menu)
{
    reinitMenu(menu);
    super.onPrepareOptionsMenu(menu);
}
 
protected void reinitMenu(Menu menu)
{
    menu.findItem(R.id.menu_refresh).setVisible(
        !getFActivity().isLoading());
}

When data is loaded via AsyncTask in the onPostExecute method, notifyDataSetChanged is called sequentially on the model bound to the ListView, setSupportProgressBarVisibility and invalidateOptionsMenu.

    Override
        protected void onPostExecute(Void result)
        {
            super.onPostExecute(result);
            for (int i = 0; i < 10; i++)
            {
                adapter.items.add(i);
            }
            adapter.notifyDataSetChanged();
            activity.stopLoading();
        }
…
    void stopLoading()
    {
        if (loaders.decrementAndGet() == 0)
        {
            setSupportProgressBarIndeterminateVisibility(false);
            invalidateOptionsMenu();
        }
    }

This code in many cases "breaks" the view of the ActionBar. Icons disappear, an empty space appears on the right instead of
them . ; then the ActionBar will look correct. But I suspect that this is not the only possible reason for such a "breakdown". Perhaps someone has come across a similar one and knows how to properly deal with this problem?
