Bug #5616: * /lib/net/imap.rb exception in IMAP.new when get_response returns nil

The error occurred in ruby 1.8.7 when connecting to a buggy IMAP server. The error message was: Undefined method 'name' in imap.rb
It is this piece of code in line 915 (line 1067 in ruby 1.9.3):

  @greeting = get_response
  if @greeting.name == "BYE"
    @sock.close
    raise ByeResponseError, @greeting
  end

after a little search I saw that the function 'get_response' returns nil if the buffer is empty:

def get_response
  buff = ""
  while true
    ...
  end
  return nil if buff.length == 0
    ...
  return @parser.parse(buff)
end
