Solve the following python programming problem given the following code:
def handle(verified_contact, text, msg = None) : 
    user = (verified_contact.owner if verified_contact else None) 
    domain = user.domain 
    if (domain and (not ILSGatewayConfig.for_domain (domain))) :

    Fix the buggy line: handler_class = choose_handler (location_needed_handlers, handlers)

#Here is Python program to fix the buggy line: handler_class = choose_handler (location_needed_handlers, handlers)
