Hello Rex,
Here is the output of "qdbus":
http://pastebin.com/raw.php?i=CicNz0hV

Also, I have what MIGHT be a related issue that I just saw for the first 
time: At least Dolphin and Konqueror will not load any directories.  The 
window opens and looks normal except for the fact that the area where 
the directories/files would be displayed is blank.  Dolphin gives me a 
really good error message:

Could not start process Unable to create io-slave:
klauncher said: Error loading 'kio_file'.

Here is the output of "qdus", as well as a strace for three different 
applications that exhibit this issue:
http://tinypaste.com/d4d1b2c1 (dolphin)
http://tinypaste.com/d2d9bc1c (konqueror)
http://tinypaste.com/35f50887 (ksysguard)
http://tinypaste.com/4761c6cb (qdbus)

If you need any more information, let me know.
