Solve the following python programming problem given the following code:
def load(self, source, default = False, **kwargs) : 
    def _load(graph, source) : 
        try : 
            return graph.load (source, ** kwargs) 
except : 
            pass 
try : 
            return graph.load (source, format = 'n3', ** kwargs) 
except : 
            pass 
try : 
            return graph.load (source, format = 'nt', ** kwargs) 
except : 
            raise Exception (('Could not load %s as either RDF/XML, N3 or NTriples' % source)) 
if (not rdflib.plugins.sparql.SPARQL_LOAD_GRAPHS) : 
        if default : 
            self.graph += self.dataset.get_context (_load) 
else : 
        if default : 
            _load (self.graph, source) 
else : 
            _load (self.dataset, source) 

    
    

    Fix the buggy line: self.graph += self.dataset.get_context (_load)

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

self.graph += self.dataset.get_context (source)
