No.  It shows that Evolution uses defferent path than Nautilus.
Seems like Nautilus uses GIO (discovered by Nautilus' behavior, I'm
did'n look into sources), while Evolution uses Gnome-VFS as your
investigation shows.

If I recall and understand correctly,
these pathes are different since glib-2.16,

Appropriate ChangeLog entry is (gio/ChangeLog):

  6461      alexl 2008-02-06  Alexander Larsson  <alexl at redhat.com>
  6461      alexl
  6461      alexl 	* gdesktopappinfo.c:
  6461      alexl 	Update to use both mimeapps.list and
  6461      alexl 	defaults.list as discussed on xdg list.

Workaround: use hand-written defaults.list
(~/.local/share/applications/defaults.list) for enforse need
association.
