Frame around the desktop when dragging

[Vincent Noel <vincent noel gmail com>]

Hey all,
Recently, a nice feature was added to drag-n-drop in nautilus : a
frame appears in the window that is the drag-and-drop target.
While I think this is useful and adds to usability, it seems to
confuse some users :

I'm not saying the feature should be totally disabled, but maybe it
would be possible to disable the feature when the drag target is the
desktop window.

Cheers
Vincent
