gnome ain't show /mnt/dvdram0/

[hahlo <hahlo blinkenshell org>]

at the terminal I can: hahlo@hahlo-ThinkPad-T430:~$ nautilus 
/mnt/dvdram0/ and it works
but tell in the terminal:"Nautilus-Share-Message: 18:23:49.591: Called 
"net usershare info" but it failed: Lapsiprosessin “net” käynnistäminen 
epäonnistui (No such file or directory)
Nautilus-Share-Message: 18:25:36.587: Called "net usershare info" but it 
failed: Lapsiprosessin “net” käynnistäminen epäonnistui (No such file or 
directory)

(eog:3932): EOG-WARNING **: 18:25:41.960: Tiedoston

is it a bug or feature?
