Description of problem:
Cannot unmount USB (CF) storage from in GNOME.
If I mount removoable media (I have a USB attached "6-in-1" media reader) while 
in GNOME I cannot umount until I log out.  If I simply mount via an xterm and 
do _nothing_ else (not even an "ls") I can then not umount without getting a 
message similar to:
umount2: Device or resource busy
umount: /mnt/usb is busy

I am NOT leaving any nautilus browsers open / focused on the mount point.
I do NOT have any users in the mount

"fuser" shows nada

I can mount and unmount to my hearts content from command line on VC1 even if 
the GUI is logged in.


Version-Release number of selected component (if applicable):
unsure - Nautilus?  mount?

How reproducible:
Always

Steps to Reproduce:
1. Log into GNOME
2. Mount USB storage
3. Try to unmount
    

Actual Results:  see error test above

Expected Results:  umount w/o complaint

Additional info:

I can provide any system details required
(sda is Serial ATA, sdb is CF removable media)
