Description of problem:
If two usb disks are mounted in the KDE desktop, then if one is umounted by
selecting the "safely remove" option after right clicking its icon, then the
second disk icon no longer gives the same option when right clicked.

Version-Release number of selected component (if applicable):
kdelibs-3.5.4-0.3.fc5

How reproducible:
Every time

Steps to Reproduce:
1. Plug in two usb disks one after the other
2. Allow the system to mount both disks
3. Right click on the desktop icon for one disk
4) The disk correctly umounts and the icon remains on the desktop.
5) Now right click the other disk icon
6) the option of safely remove is not presented for this second disk

  
Actual results:
Second usb disk cannot be umounted using right click on the desktop, although it
can be umounted from a root konsole.

Expected results:
Second usb disk should also have the option to safely remove by right clicking
the desktop icon
