Title:
  Fontconfig error output due to malformed conf file

Status in fontconfig package in Ubuntu:
  Confirmed

Bug description:

  Installing breakpad exception handler for appid(steamwebhelper)/version(1422637902)

  Above output is produced, eg by steam when running a game.

  The fontconfig error lines can be verified with "fc-cache -v | grep -i
  err".

  The offending section is around original lines 70, 78:

  <match target="font">
    <test name="scalable" compare="eq">
      <bool>false</bool>
    </test>
    <test name="pixelsizefixupfactor" compare="not_eq">
      <double>1.0</double>
    </test>
    <edit name="matrix" mode="assign">
      <times>
        <name>matrix</name>
        <matrix>
          <name>pixelsizefixupfactor</name> <double>0</double>
          <double>0</double> <name>pixelsizefixupfactor</name>
         </matrix>
      </times>
    </edit>
    <edit name="size" mode="assign">
      <divide>
        <name>size</name>
        <name>pixelsizefixupfactor</name>
      </divide>
    </edit>
  </match>

  Note that the <matrix> element has 2 <name> child elements when it
  should only have 1. Removal of the second
  "<name>pixelsizefixupfactor</name>" solves the error. After this
  removal neither fc-cache nor steam report an "Fontconfig error:".

  The documentation for fonts.conf, eg http://linux.die.net/man/5/fonts-
  conf, suggests that the <matrix> element should hold 4 <double>
  elements:

  ><MATRIX>
  >
  >This element holds the four <double> elements of an affine transformation.

  But it appears not to produce an error when only 2 elements are
  present (and does produce an error here when there are 4, for me).
