CD eject but not unmount when using drive button, likely regression-release Bug #476654

[DrShushen]

When ejecting the cd/dvd using the drive button, the cd/dvd is not unmounted - i.e. it's still shown on the desktop, in the files etc. Similar bug was reported in the past (Bug #476654) but it seems to be happening again now on 11.10.
