Where are you burn:///?

["jorge o. castro" <jorge@whiprush.org>]

I just realized that none of my sid boxes has a "burn:///" that works. I 
get

"burn:///" is not a valid location. Please check the spelling and try 
again."

Is nautilus-cd-burner supposed to be a seperate package? (I can't find a 
seperate package) or is there some setting somewhere I missed? Thanks.
