Nautilus uses the icon specified in the .desktop file (your example
desktop file doesn't contain a valid Icon value, that may be the reason
why you don't see the icon). Konquerors behavior is inconsistent, i.e.
kdesktop displays the name of the .desktop file while file manager
windows display the file name (IIRC), so as attacker just make sure to
place the file on the desktop and voila (which is even worse, since the
desktop is the default download location for files in several browsers).
ROX, dunno, displays a binary icon for the file, but still executes it
properly, some people might call that secure... read the XDG threads.

But for your example, there's indeed an easy way to improve Thunars
security there.

There's no consensus yet.
