xaos doesn't work as screensaver as it doesn't take "window-id" option

Binary package hint: xaos

Hi all,
     I am using xscreensaver 5.04-2ubuntu2 . I tried to use Xaos as screensaver & I get this output :-

shirish@Mugglewille:~$ xscreensaver-demo

After clicking on xaos I don't see any preview & the CLI gives this output :-

window-id:unknown function
