Steps to reproduce:

  1. Compile Emacs with "make CFLAGS='-g -DENABLE_CHECKING'"
  2. emacs -Q
  3. (x-family-fonts) C-j

Result:

  .../src/xfaces.c:1763: Emacs fatal error: assertion failed: VECTORLIKEP((vec))

The value of `vec' is from font_list_entities, whose return value is
of cons.

1758	    {
1759	      CHECK_STRING (family);
1760	      font_parse_family_registry (family, Qnil, font_spec);
1761	    }
1762	  vec = font_list_entities (frame, font_spec);
1763	  nfonts = ASIZE (vec);
1764	  if (nfonts == 0)
1765	    return Qnil;
1766	  if (nfonts > 1)
1767	    {

This is a left-over from the 2009-07-14 change to font_list_entities.
I've checked in a fix, thanks.
