Other strange report from xdg_mime_get_mime_type_for_file():

directory,device,loopback and all other linux-oriented files.

All this file will be reported as 'application/octet-stream'.

So i think I have to check this special case myself, but I don't know
what mime-name give to the files to be standard, ex:
-directory should be 'application/x-directory' or 'inode/directory' or what?
-I have no idea for other type (device, ecc).
