Buggy source:
@Override protected void onResume(){
  super.onResume();
  showRecentChanges();
  PreferenceScreen screen=getPreferenceScreen();
  SharedPreferences sharedPreferences=screen.getSharedPreferences();
  Set<Integer> appWidgetIds=new HashSet<Integer>();
  WidgetRepository repository=new AndroidWidgetRepository(getBaseContext());
  for (  int i : repository.getIds()) {
    appWidgetIds.add(i);
  }
  if (!appWidgetIds.contains(mAppWidgetId)) {
    repository.addWidgetId(mAppWidgetId);
  }
  int widgetSize=sharedPreferences.getInt("String_Node_Str",0);
  if (widgetSize == 0 || widgetSize == 1) {
    PreferenceScreen stock_setup=(PreferenceScreen)findPreference("String_Node_Str");
    for (int i=5; i < 11; i++)     removePref(stock_setup,"String_Node_Str" + i);
  }
  if (widgetSize == 1 || widgetSize == 3) {
    PreferenceScreen widget_views=(PreferenceScreen)findPreference("String_Node_Str");
    removePref(widget_views,"String_Node_Str");
    removePref(widget_views,"String_Node_Str");
    removePref(widget_views,"String_Node_Str");
    removePref(widget_views,"String_Node_Str");
  }
  String install_date=getAppPreferences().getString("String_Node_Str",null);
  if (DateTools.elapsedDays(install_date) < 30)   removePref("String_Node_Str","String_Node_Str");
  Map<String,?> map=sharedPreferences.getAll();
  for (  String key : map.keySet())   updateSummaries(sharedPreferences,key);
  findPreference("String_Node_Str").setSummary("String_Node_Str" + VersionTools.BUILD);
  updateSummaries(sharedPreferences,"String_Node_Str");
  updateSummaries(sharedPreferences,"String_Node_Str");
  updateSummaries(sharedPreferences,"String_Node_Str");
  updateSummaries(sharedPreferences,"String_Node_Str");
  sharedPreferences.registerOnSharedPreferenceChangeListener(this);
}

Fixed version (ground truth):
@Override protected void onResume(){
  super.onResume();
  showRecentChanges();
  PreferenceScreen screen=getPreferenceScreen();
  SharedPreferences sharedPreferences=screen.getSharedPreferences();
  int widgetSize=sharedPreferences.getInt("String_Node_Str",0);
  if (widgetSize == 0 || widgetSize == 1) {
    PreferenceScreen stock_setup=(PreferenceScreen)findPreference("String_Node_Str");
    for (int i=5; i < 11; i++)     removePref(stock_setup,"String_Node_Str" + i);
  }
  if (widgetSize == 1 || widgetSize == 3) {
    PreferenceScreen widget_views=(PreferenceScreen)findPreference("String_Node_Str");
    removePref(widget_views,"String_Node_Str");
    removePref(widget_views,"String_Node_Str");
    removePref(widget_views,"String_Node_Str");
    removePref(widget_views,"String_Node_Str");
  }
  String install_date=getAppPreferences().getString("String_Node_Str",null);
  if (DateTools.elapsedDays(install_date) < 30)   removePref("String_Node_Str","String_Node_Str");
  Map<String,?> map=sharedPreferences.getAll();
  for (  String key : map.keySet())   updateSummaries(sharedPreferences,key);
  findPreference("String_Node_Str").setSummary("String_Node_Str" + VersionTools.BUILD);
  updateSummaries(sharedPreferences,"String_Node_Str");
  updateSummaries(sharedPreferences,"String_Node_Str");
  updateSummaries(sharedPreferences,"String_Node_Str");
  updateSummaries(sharedPreferences,"String_Node_Str");
  sharedPreferences.registerOnSharedPreferenceChangeListener(this);
