Android: getView() called twice in custom adapter

I'm setting a custom SimpleCursorAdapter to a ListView. For some reason FriendAdapter's getView() is called twice for every item in the DB. After some investigation (I have no wrap_content in my contact_list.xml), I can still not figure out why.

What could be the reasons? Anybody can help?

Thanks

ContactSelection.java

public class ContactSelection extends ListActivity {

    private WhipemDBAdapter mDbHelper;  

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        mDbHelper = new WhipemDBAdapter(this);
        mDbHelper.open();     

        setContentView(R.layout.contact_list);        

        Cursor c = mDbHelper.fetchAllFriends();
        startManagingCursor(c);     
        String[] from = new String[] {};
        int[] to = new int[] {};

        setListAdapter(new FriendAdapter(this, R.layout.contact_row, c, from, to));

        getListView().setItemsCanFocus(false);
        getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
    }

    @Override
    protected void onResume() {
        super.onResume();
        mDbHelper.open();
    }

    @Override
    protected void onPause() {
        super.onPause();
        mDbHelper.close();
    }
}

FriendAdapter.java

public class FriendAdapter extends SimpleCursorAdapter implements OnClickListener {

    private Context mContext;
    private int mLayout;
    private Cursor mCursor;
    private int mNameIndex;
    private int mIdIndex;
    private LayoutInflater mLayoutInflater; 
    private final ImageDownloader imageDownloader = new ImageDownloader();  

    private final class ViewHolder {
        public TextView name;
        public ImageView image;
        public CheckBox checkBox;
    }

    public FriendAdapter(Context context, int layout, Cursor c, String[] from, int[] to) {
        super(context, layout, c, from, to);

        this.mContext = context;
