Solve the following python programming problem given the following code:
def get(self, key, callback) : 
    key = b64encode (key) 
    def process_get(stream, cb, data) : 
        if (data [0 : 3] == 'END') : 
            cb (None) 
else : 
            (status, k, flags, content_length) = data.strip ().split (' ') 
            def wrapped_cb(f) : 
                return (lambda data : f (b64decode (data))) 
stream.read_bytes (int (content_length), wrapped_cb (cb)) 
            stream.read_until ('\r
END\r
', (lambda d : d)) 
self.stream.write (('get %s\r
' % key)) 
    self.stream.read_until ('\r
', functools.partial (process_get, callback.stream, callback)) 

    
    

    Fix the buggy line: self.stream.read_until ('\r
', functools.partial (process_get, callback.stream, callback))

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

self.stream.read_until ('\r
