Hello.

This commit introduced the error, I suspect the error is present on all ports:

message:
  * font.c (font_list_entities): Do not add empty vector to font cache.
  (font_matching_entity): Likewise.  If matching entity is found, insert
  1-item vector with this entity instead of entity itself (Bug#17125).

There is an issue when trying to set the font of face in recent versions
of emacs build for OSX.

Evaluating this form works as expected:

    (set-face-font 'region 
"-*-Menlo-normal-normal-normal-*-12-*-*-*-m-0-iso10646-1")

It used to be that one could also say something like this:

    (set-face-font 'region  "bitstream vera sans mono-26")

but when I try to do that on a newly built emacs, I get this stack
trace:

    Debugger entered--Lisp error: (wrong-type-argument font [#<font-entity ns 
apple Menlo nil iso10646-1 medium normal normal 0 nil 100 0 nil>])
      internal-set-lisp-face-attribute(region :font "bitstream vera sans 
mono-26" 0)
      set-face-attribute(region nil :font "bitstream vera sans mono-26")
      set-face-font(region "bitstream vera sans mono-26")
      eval((set-face-font (quote region) "bitstream vera sans mono-26") nil)
      eval-last-sexp-1(nil)
      eval-last-sexp(nil)
      call-interactively(eval-last-sexp nil nil)
      command-execute(eval-last-sexp)

This works fine in the emacs-24 branch, so it is a new error.  I will bisect it 
soon.
Changes to xfaces.c is probably it.
