IMO both thumbnails are valid. You may use the thumb of "the other size" to 
create one of the right size. Or you use the original image for this. But in the 
end, none of the thumbnails are invalid only in different sizes. This is exactly 
the purpose of the spec. The reason for the different size directories were that 
some programs use very large previews and other smaller ones. To prevent 
downscaling thumbs for smaller-previews every time these (to some extent 
arbitrary) sizes and their directories have been choosen.

Thumbnails should be deleted only if they are outdated or the original image has 
been disapeared.
