[lubuntu] Error message Location is not mountable

Computer recently up graded to 16.04 from 15.10, if I insert a DVD I get the normal small window with the list of available options in it, if I insert a CD I get the Error message Location is not mountable, now I know a music CD isn't mountable, but I used to get the small window listing the options. Now whilst this isn't a major problem, I can access the disc with VLC and I don't use discs very often, but its aoying.
