Crash after phone wake up if SimpleFormDialog was stay in foreground.

There is a problem with SimpleFormDialog if it was in foreground when device going to sleep. When it wake up application crashes because of getDialog() is null in the following code:

@Override
protected void onDialogShown() {
    // resize dialog when keyboard is shown to prevent fields from hiding behind the keyboard
    if (getDialog().getWindow() != null) {
        getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
    }

    setPositiveButtonEnabled(posButtonEnabled());
    requestFocus(0);
}

If I add null check to it - if (getDialog() != null && getDialog().getWindow() != null) - the crash disappears.
