Thanks, this sure seems to be my problem .  
/home/mythtv/.mythtv/channels is empty.  And I know they were there 
before I upgraded.   I re-ran

$ mkiconmap.pl
$ mythfilldatabase --import-icon-map iconmap.xml --update-icon-map

That's all the docs say to do, but the directory is still empty.  What's 
supposed to grab the .jpg's?  Did I miss a step?
