I'm no expert but I believe that the first entry that matches wins: for
"application/pdf" e.g. in this case, if /usr/bin/xpdf is present and
executable and the display test succeeeds, xpdf will be used. Otherwise
it's going to search further: if evince is present and the display test
succeeds, evince will be used.

You probably want to experiment by adding entries to ~/.mailcap, so that
you don't mess up the system one: entries in ~/.mailcap override. I just
have the bare minimum in mine:

application/pdf; xpdf -q %s

Next question: since xpdf is available and /etc/mailcap prefers it, why
is nautilus using evince? Doesn't it use mailcap? I guess not, although
I don't know for sure[fn:1], but it wouldn't surprise me if it did its
own thing: there are way too many cooks in this kitchen.

Footnotes:

[fn:1] as you might guess, I don't use nautilus: I have emacs - why would
       I use anything else?
