Must be a particular problem on your system and/or browser.

When I do the same on my Linux here I see:

file 10kB
10kB: data

file -i 10kB
10kB: application/octet-stream; charset=binary

and my Firefox browser sets the mimetype also correct to  
application/octet-stream:
Mozilla/5.0 (X11; U; Linux i686; de; rv:1.9.0.10) Gecko/2009042315  
Firefox/3.0.10
