Well, in my interpretation, the mime data just says that it's can handle PDF's, 
not necessarily that it's at PDF reader. If a PDF is opened with Gimp, it shows 
an interface for importing it as images, so I don't feel like it's a mistake 
for Gimp to mark it's self as being able to handle PDF's. If we make actual PDF 
readers have priority over Gimp somehow, Gimp will still be under the list of 
suggested applications when one right clicks on a *.pdf file in a file manager, 
but making this change would completely remove Gimp as an option. 

From the perspective of Gimp developers, they have no power to make Gimp's 
mimedata cause ideal behaviour on, because mimedata is simply not very 
versatile, so listing Gimp as being able to handle application/pdf isn't a 
mistake on their part.

The best solution might be to create mimeapps.list files that take precedence 
over mimeinfo.cache. I'm not sure which package it should go in though.
