Bug is not fixed for me with shared-mime-info 0.16-1.  The issue is a bit
subtler than is represented in this bugzilla: many programs create eps with
exactly the same routines as .ps, but simply name them  differently and include
only one page.  So, practically, one can have an .eps file that behaves like an
.eps file in every way, but file (and other magic routines) decide are
postscript rather than encapsulated postscript. The upstream bugs deal with this
situation, but the Ubuntu bug focuses only on the case where .eps was properly
defined and identified.
So, the security warning still on my computer with shared-mime-info 0.16-1:

file document.eps
document.eps: PostScript document text conforming at level 3.0

There may be an upstream fix that hasn't been properly applied/propogated.  By
placing the override.xml shown in comment 7 of
https://bugs.freedesktop.org/show_bug.cgi?id=2686
(https://bugs.freedesktop.org/attachment.cgi?id=2344) in
/usr/share/mime/packages and running update-mime-database /usr/share/mime/,
nautilus handles .eps again.  To test, one can create an .eps file with the
following command in R:

user:~ $ R
> postscript("test.eps"); plot(1:10); dev.off()
> q()
user:~ $ file test.eps
test.eps: PostScript document text conforming at level 3.0
user:~ $
