DialogFragment with AppCompatDialog crashes if STYLE_NO_TITLE is set

Question

I'm trying to use the new material-themed dialogs with fragments in AppCompat v22.1. According to Chris Banes, to do this:

Just return new AppCompatDialog(getActivity(), getTheme()) from onCreateDialog(Bundle).

Setting this up:

public class MyFragment extends DialogFragment
{
    public MyFragment() { }

    public Dialog onCreateDialog(Bundle savedInstanceState) {
        return new AppCompatDialog(getActivity(), getTheme());
    }

    ...
}

works perfectly in the normal case; the dialog is correctly themed and everything. However, when we try to show a dialog with the STYLE_NO_TITLE option:

 MyFragment fragment = new MyFragment();
 fragment.setStyle(DialogFragment.STYLE_NO_TITLE, 0);
 fragment.show(getSupportFragmentManager(), "DIALOG");

it causes the following exception and crash:

I guess the problem might be related to DialogFragment calling requestWindowFeature() instead of supportRequestWindowFeature() (?)

Is there any workaround for this issue?

This was a bug in AppCompat v22.1 which was fixed in v22.1.1.

It broke again in v23 and was fixed once more, in v23.0.1.

It's working ok as of this writing.
