I guess so. I don't know what KDE/GNOME do when given an invalid desktop

Yes - things like JPEG file, word processor document etc are pretty much 
guaranteed to be there.

This is what will save us ...

That was the original proposal. There have been lots of alternatives 
proposed, but can anybody think of a good reason why we shouldn't do 
this? Aaron gave the best IMHO - that there are many "legit" icons a 
malicious file could use that aren't mime icons. Fair point. But, is 
this reasoning strong enough to say we should not do it? I am not sure.
