So I recently updated the superbuild to use a newer fontconfig for the
following reasons:

  - to use the system font configuration settings (from /etc) rather
    than starting up with nothing (and looking ugly);
  - the old fontconfig warned about new configuration files;
  - updated to use a new fontconfig.

Now it seems the new fontconfig doesn't like the old configuration files
:( . In any case, these have only ever been just warnings and may be
ignored.

Can you get a backtrace from the segfault? I see nothing that indicates
that the segfault is from fontconfig. I suppose we could add an option
to use a system fontconfig rather than building our own.
