How to create an Android Tabbed Dialog containing fragments?

Can anyone point me to an example or show me how to create a simple Tabbed Dialog in Android where the contents of each tab are Fragments? All the examples/tutorials I have found are about Fragments and Tabs, but nothing specific to DialogFragments.

The documentation for FragmentTabHost shows how to create tabs within normal fragments using getChildFragmentManager(). I'm assuming this should also work when the fragment is a DialogFragment but when I try it I get:

java.lang.IllegalStateException: Fragment does not have a view at android.support.v4.app.Fragment$1.findViewById(Fragment.java:1425)
at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:901)
at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:1088)
...

Here's my code for setting up the view (which is then passed to AlertDialog.setView()):

private void setupView(View v) {
    mTabHost = (FragmentTabHost) v.findViewById(android.R.id.tabhost);

   mTabHost.setup(getActivity(), getChildFragmentManager(), R.id.realtabcontent);

   mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator("Tab1"),
            MyDialogFragment.class, null);
}
