Comment 5 for bug 1010714

2nd variation of bad behavior

Test Case:
Mount an internal drive, lock to the Unity launcher
Unmount the drive, then log out/in or do a full restart
2 icons for the same drive will show in the launcher, drive is not mounted. Both icons can be removed separately with a r. click > Unlock from Launcher'

Downgrading gvfs* to the 1.13.0-0ubuntu1 version & none of this happens
