Solve the following python programming problem given the following code:
@ mock.patch.object (utils, 'rmtree_without_raise', autospec = True) 
@ mock.patch.object (image_cache, '_fetch', autospec = True) 
def test_temp_images_not_cleaned(self, mock_fetch, mock_rmtree) : 
    def _fake_fetch(ctx, uuid, tmp_path, * args) : 
        with open (tmp_path, 'w') as fp : 
            fp.write (('TEST' * 10)) 
self.cache.clean_up () 
        self.assertTrue (os.path.exists (tmp_path)) 
mock_fetch.side_effect = _fake_fetch 
    master_path = os.path.join (self.master_dir, 'uuid') 
    dest_path = os.path.join (tempfile.mkdtemp (), 'dest') 
    self.cache._download_image ('uuid', mock_rmtree, dest_path) 
    self.assertTrue (mock_rmtree.called) 

    
    

    Fix the buggy line: self.cache._download_image ('uuid', mock_rmtree, dest_path)

#Here is Python code to fix the buggy line: self.

self.cache._download_image ('uuid', master_path, dest_path)
