Description of Problem:
diskusage_applet shows info for /dev/shm which isn't very useful
Steps to Reproduce:
1. start diskusage_applet
2. right click on it
3. choose filesystems -> /dev/shm is there
Show stats for a "filesystem" that is always full
No /dev/shm in the display
This defect is considered SHOULD-FIX for Fairfax.
We no longer seem to have a diskusage applet in rawhide.
