Solve the following python programming problem given the following code:
def __init__(self, decoded_data) : 
    self.header = self.header 
    self.decoded_data = decoded_data 
    def fill_group(group, data) : 
        for layer in data ['layers'] : 
            index = layer ['index'] 
            if ('layers' in layer) : 
                sub_group = Group (group, index, []) 
                fill_group (sub_group, layer) 
                group._add_layer (sub_group) 
else : 
                group._add_layer (Layer (group, index)) 
self._psd = self 
    fake_root_data = { 
        'layers' : group_layers (decoded_data), 
        'index' : None, 
} 
    root = _RootGroup (self, None, []) 
    fill_group (root, fake_root_data) 
    self._fake_root_group = root 
    self.layers = root.layers 
    self.embedded = [Embedded (linked) for linked in self._linked_layer_iter ()] 

    
    

    Fix the buggy line: self.header = self.header

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

self.header = decoded_data.header
