Error with Fragments: "java.lang.IllegalStateException: FragmentManager is already executing transactions"

I'm having a small problem when creating fragments, it's that I get an Exception as if getSupportFragmentManager was already running.

The error:

  

E / AndroidRuntime: FATAL EXCEPTION: main                     Process: jhon.casique.baccus, PID: 30971                     java.lang.IllegalStateException: FragmentManager is already executing transactions                         at android.support.v4.app.FragmentManagerImpl.execPendingActions (FragmentManager.java:1649)                         at android.support.v4.app.FragmentManagerImpl.executePendingTransactions (FragmentManager.java:589)                         at android.support.v4.app.FragmentTabHost.onAttachedToWindow (FragmentTabHost.java:285)                         at android.view.View.dispatchAttachedToWindow (View.java:14607)                         at android.view.ViewGroup.dispatchAttachedToWindow (ViewGroup.java:2837)                         at android.view.ViewGroup.addViewInner (ViewGroup.java:4349)                         at android.view.ViewGroup.addView (ViewGroup.java:4146)                         at android.view.ViewGroup.addView (ViewGroup.java:4087)                         at android.view.ViewGroup.addView (ViewGroup.java:4060)                         at android.support.v4.app.FragmentManagerImpl.moveToState (FragmentManager.java:1124)                         at android.support.v4.app.FragmentManagerImpl.moveToState (FragmentManager.java:1290)                         at android.support.v4.app.BackStackRecord.run (BackStackRecord.java:801)                         at android.support.v4.app.FragmentManagerImpl.execPendingActions (FragmentManager.java:1677)                         at android.support.v4.app.FragmentManagerImpl $ 1.run (FragmentManager.java:536)                         at android.os.Handler.handleCallback (Handler.java:739)                         at android.os.Handler.dispatchMessage (Handler.java:95)                         at android.os.Looper.loop (Looper.java:234)                         at android.app.ActivityThread.main (ActivityThread.java:5526)                         at java.lang.reflect.Method.invoke (Native Method)                         at com.android.internal.os.ZygoteInit $ MethodAndArgsCaller.run (ZygoteInit.java:726)                         at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:616)

MY CODE

 public class WineryFragment extends Fragment {
    @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
     super.onCreateView(inflater, container, savedInstanceState);

    View root = inflater.inflate(R.layout.activity_winery, container, false);

    //Creating wines.
    Wine bembibre =new Wine(
            "Bembibre",
            "Tinto",
            R.drawable.bembibre,
            "Dominio de Tares",
            "http://www.dominiodetares.com/portfolio/bembibre/",
            "Este vino muestra toda la complejidad y la elegancia de la variedad Mencía. En fase visual luce un color rojo picota muy cobierto con tonalidades violáceas en el menisco. En nariz aparecen recuerdos frutales muy intensos de frutas rojas (frambuesa, cereza) y una potente ciruela negra asi como tonos florales de la gama de las rosas y violetas, vegetales muy elegantes y complementarios, hojarasca verde, tabaco y maderas aromáticas (sándalo) que le brindan un troque ciertamente perfumado",
            "El Bierzo",
            5);
    bembibre.addGrape("Mencía");

    Wine vegaval =new Wine(
            "Vegaval",
            "Tinto",
            R.drawable.vegaval,
            "Miguel de Calatayud",
            "http://www.vegaval.com/es",
            "Este vino es para gente guay como Jhon ó Gabriela, el gordo no, el no es guay",
            "Valdepeñas",
            4);
    vegaval.addGrape("Tempranillo");

    //View for fragment add tabs.
    FragmentTabHost tabHost = (FragmentTabHost) root.findViewById(android.R.id.tabhost);
    tabHost.setup(getActivity(), getActivity().getSupportFragmentManager(), android.R.id.tabcontent);


    //Adding the first tab.
    Bundle arguments = new Bundle();
    arguments.putSerializable(WineFragment.ARG_WINE, bembibre);
    tabHost.addTab(tabHost.newTabSpec(bembibre.getName()).setIndicator(bembibre.getName()), WineryFragment.class, arguments);

    //Adding the second tab
    arguments = new Bundle();
    arguments.putSerializable(WineFragment.ARG_WINE, vegaval);
    tabHost.addTab(tabHost.newTabSpec(vegaval.getName()).setIndicator(vegaval.getName()), WineryFragment.class, arguments);

    return root;
}
}

And this is the code of the activity

package jhon.casique.baccus.controller.activity;

import android.support.v4.app.Fragment;

import jhon.casique.baccus.controller.fragments.WineryFragment;

public class WineryActivity extends FragmentContainerActivity {
    @Override
    protected Fragment createFragment() {
         return new WineryFragment();
    }
}
