bgo533891 - disallow DnD from the file list into itself
2008-05-27  Federico Mena Quintero  <federico@novell.com>

	http://bugzilla.gnome.org/show_bug.cgi?id=533891 - Don't allow
	drag and drop from the file list into itself, as it doesn't make
	sense (it would just change the current folder).

	* gtk/gtkfilechooserdefault.c (file_list_dest_targets): Use
	GTK_TARGET_OTHER_WIDGET so we don't DnD from the file list into
	itself.
