Description of Problem:
If I mount CD-ROM from nautilus and open a file
with an application, after closing that
application nautilus keeps busy the device.

Steps to reproduce the problem:
1. Right click on desktop, mount CD-ROM and open
from icon.
2. Open a file (such as .jpeg) with nautilus then
close it.
3. Right click on CD-ROM icon, -> eject ; now it
really ejects, *but*:

2b) Open a file (such as the same .jpeg as above)
with another application (say eog) end then close
it and close the device window.
3b) Right click on CD-ROM -> eject ; now it cannot
eject and says that the resource is busy;

*Moreover*
Let us start from point 3b) when nautilus says
that the resource is busy. Now:
1) I logout to gdm (I use gdm)
2) go to another virtual console (say tty2) and
login as root
3) unmounting CD-ROM is now ok
*but*
2b) re-login (in gnome with nautilus) without
having unmounted CD-ROM
3b) right click on CD-ROM icon -> eject ; it
doesn't eject and says the resource is busy

Actual Results:
Nautilus keeps busy CD-ROM when I open files in
CD-ROM with applications not in nautilus (e.g. eog
for graphics, rhythmbox for music, and so on) and
doesn't allow eject.

Expected Results:
Nautilus frees the device as I close applications
and the window of the device

How often does this happen? 
always
