I put in a video DVD and use it. After finishing, I eject by pressing the physical drive button. The DVD icon in the gnome-shell dock remains. I cannot then make the icon go away by right-clicking and using the eject menu entry.

If I instead rightclick the DVD icon to eject while the disc is still in the drive, the icon disappears as expected.

I've tried reinserting the DVD and then using the icon menu eject option, but that doesn't remove the icon either.

So far, restarting the whole gui is the only way to clean up these disconnected icons that I've found.
