(I understand the reason, but am disappointed that the magic does not work for 
all files which I thought it does (for local files))

Is this identification consistent, both in display and handlers? If not, it 
should be enforced!

I always praised KDE to be better here than e.g. MS Windows, where files are 
treated differently if the type is displayed as symbol and if the default 
handler is searched and called. Like in an attachment named NakedZack.png, 
shown as image file, which is in reality an executable attacking your graphic 
card.
