Buggy source:
protected void signInError(int messageId,String clientResponse){
  AnalyticsTracker.track(Stat.LOGIN_FAILED);
  FragmentTransaction ft=getFragmentManager().beginTransaction();
  SignInDialogFragment nuxAlert;
  if (messageId == org.wordpress.android.R.string.account_two_step_auth_enabled) {
    nuxAlert=SignInDialogFragment.newInstance(getString(org.wordpress.android.R.string.nux_cannot_log_in),getString(messageId),org.wordpress.android.R.drawable.noticon_alert_big,2,getString(org.wordpress.android.R.string.cancel),getString(org.wordpress.android.R.string.visit_security_settings),"String_Node_Str",SignInDialogFragment.ACTION_OPEN_URL,0);
    Bundle bundle=nuxAlert.getArguments();
    bundle.putString(SignInDialogFragment.ARG_OPEN_URL_PARAM,"String_Node_Str");
    nuxAlert.setArguments(bundle);
  }
 else {
    if (messageId == org.wordpress.android.R.string.username_or_password_incorrect) {
      handleInvalidUsernameOrPassword(messageId);
      return;
    }
 else     if (messageId == org.wordpress.android.R.string.invalid_url_message) {
      showUrlError(messageId);
      endProgress();
      return;
    }

    }
  }
  ft.add(nuxAlert,"String_Node_Str");
  ft.commitAllowingStateLoss();
  endProgress();
}

Fixed version (ground truth):
protected void signInError(int messageId,String clientResponse){
  AnalyticsTracker.track(Stat.LOGIN_FAILED);
  FragmentTransaction ft=getFragmentManager().beginTransaction();
  SignInDialogFragment nuxAlert;
  if (messageId == org.wordpress.android.R.string.account_two_step_auth_enabled) {
    nuxAlert=SignInDialogFragment.newInstance(getString(org.wordpress.android.R.string.nux_cannot_log_in),getString(messageId),org.wordpress.android.R.drawable.noticon_alert_big,2,getString(org.wordpress.android.R.string.cancel),getString(org.wordpress.android.R.string.visit_security_settings),"String_Node_Str",SignInDialogFragment.ACTION_OPEN_URL,0);
    Bundle bundle=nuxAlert.getArguments();
    bundle.putString(SignInDialogFragment.ARG_OPEN_URL_PARAM,"String_Node_Str");
    nuxAlert.setArguments(bundle);
  }
 else {
    if (messageId == org.wordpress.android.R.string.username_or_password_incorrect) {
      handleInvalidUsernameOrPassword(messageId);
      return;
    }
 else     if (messageId == org.wordpress.android.R.string.invalid_url_message) {
      showUrlError(messageId);
      endProgress();
      return;
    }
 else {
      AppLog.e(T.NUX,"String_Node_Str" + clientResponse);
      nuxAlert=SignInDialogFragment.newInstance(getString(org.wordpress.android.R.string.nux_cannot_log_in),getString(messageId),R.drawable.noticon_alert_big,3,getString(R.string.cancel),getString(R.string.contact_us),getString(R.string.reader_title_applog),SignInDialogFragment.ACTION_OPEN_SUPPORT_CHAT,SignInDialogFragment.ACTION_OPEN_APPLICATION_LOG);
