Install Plasma Resources???

[Lester M Petrie]

I installed F18 last week, and now when I log in, I get a pop up message 
box with the subject as the title.  The top line then says "Plasma 
requires an additional service for this operation".  Then there is an 
icon with "script engine" out to the side.  Finally, at the bottom, it 
says "The following service is required. Do you want to search for this 
now?", and a Continue button and a Cancel button.  When I click on the 
Continue, it comes back with "Failed to search for Plasma service" as 
the top line, and a big yellow triangle with "Could not find service in 
any configured software source"  There is a Close button that deletes 
the message box.  What is it looking for?  What do I do to make it quit 
coming up?  The only other strange thing that I observe that might 
possibly be connected is that when I try to start yumex, it fails with a 
message
YUM: The value for the SHELL variable was not found the /etc/shells file

/etc/shells has all the entries that are in it on another machine where 
yumex works.
