I guess that will be /usr/lib/apt/methods/cdrom :

$ ls -l /usr/lib/cdrom
ls: cannot access /usr/lib/cdrom: No such file or directory

I suppose that all I can do is get the source and see if I can rebuild 
with symbols. Just need the time :-(

Why has no one else seen this when it has been happening on all my 
machines for some time? Maybe use of DVDs is rare these days: I use 
jigdo to avoid multiple downloads with added advantage of 
backup/reinstall/new install media always to hand.
