Thanks, everybody.  Since everyone's questions, and the answers, all 
are related, I'll respond to Marshall, Bhushan, and Ralf all in this 
response:

I've killed and restarted plasmashell and here is the output:

I don't normally have an .xsession-errors file, but I created one and 
here is the output from starting a session:

The only recent plugin installed was the aforementioned 
kdegraphics-ksaneplugin; after removing that plugin, the output to 
.xsession-errors is the same.

Any thoughts?
