Solve the following python programming problem given the following code:
def _addressed(nick, msg, prefixChars = None, nicks = None, prefixStrings = None, whenAddressedByNick = None, whenAddressedByNickAtEnd = None) : 
    def get(group) :

return payload

    (target, payload) = msg.args 
    if (not payload) : 
        return '' 
if (prefixChars is None) : 
        prefixChars = get (conf.supybot.reply.whenAddressedBy.chars)

if any (payload.startswith, prefixStrings) : 
        return stripPrefixStrings (payload) 
else : 
        if (payload [0] in prefixChars) : 
            return payload [1 :].strip ()

                        toContinue = False 
                        while (not ircutils.isNick...

    
    

    Fix the buggy line: if ircutils.nickEqual (maybeNick, stripPrefixStrings) :
