Ah, I just remembered that I might not have changed a setting in 
Localsettings.php for ImageMagick when I upgraded to Mediawiki v1.11. 
 Sure enough, it was set to true.  I've reverted back to false as it 
was for my previous version and that fixed the problem.

Next big question:  how in the world do I find those thumbnails, to 
delete them, when Mediawiki's method of saving them to seemingly 
random folders makes it hard to find them?  I stumbled across one or 
two, but it could take forever to go through so many folders.  Is 
there an easier way?
