Fixed with this upload:
gnome-vfs2 (2.17.1-0ubuntu2) feisty; urgency=low
.
* debian/libgnomevfs2-common.links:
- don't list defaults.list, it's shipped with desktop-file-utils for Ubuntu
(Ubuntu: #62841)
** Changed in: gnome-vfs2 (Ubuntu)
Status: Confirmed = Fix Released

desktop-file-utils ships that list
