I looked on another box on the LAN, a CentOS 5, and I saw nothing
like it.  I am guessing that it is a new feature of kde or something
else in CentOS that is malfunctioning.  In a sense it is harmless, but 
creates useless noise on the net (it goes to outside dns servers)
and replaces something that should be doing something.  I'll post
on the CentOS list.
