Solve the following python programming problem given the following code:
def __init__(self, namespace, table_name = 'beaker_cache', **params) : 
    'Creates a datastore namespace manager' 
    OpenResourceNamespaceManager.__init__ (self, namespace) 
    def make_cache() : 
        table_dict = dict (created = db.DateTimeProperty (), accessed = db.DateTimeProperty (), data = db.BlobProperty ()) 
        table = type (table_name, (db.DB_Model,), table_dict) 
        return table 
self.table_name = table_name 
    self.cache = GoogleNamespaceManager.tables.setdefault (make_cache, make_cache ()) 
    self.hash = { 
        
} 
    self._is_new = False 
    self.loaded = False 
    self.log_debug = (logging.DEBUG >= log.getEffectiveLevel ()) 
    self.namespace = ('p%s' % self.namespace) 

    
    

    Fix the buggy line: self.cache = GoogleNamespaceManager.tables.setdefault (make_cache, make_cache ())

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

self.cache = GoogleNamespaceManager.tables.setdefault (table_name, make_cache ())
