[Bug 286175] Re: evince crashed with SIGSEGV in FcConfigSubstituteWithPat()

[Sagawa]

Above Wine's failure seems to be reproduced with 16-bit Windows
application.

I ran Emi Clock ( http://www003.upp.so-net.ne.jp/motosoft/ ) Windows 3.1
version, a similar failure occurred, because the code also crashes with
fstpl opcode.

I'll attach wine-emiclock16-dump.txt which produced with
libfontconfig1-dbg(2.8.0-2.1ubuntu3) and wine1.2-dbg(1.2.2-0ubuntu6)
under my x86 PC.

Bug description:
  Binary package hint: evince

  Opening a pdf document from the web.

  Crashed before it was able to render anything.

  Link: http://www.copyright.gov/history/1790act.pdf

  STEPS TO REPRODUCE:
  1. Make sure GNOME is running, evince gets fontconfig info from another library (it doesn't access FC directly)
  2. Open evince on any file, then close it.
  3. Install or remove a font (try mstcorefonts)
  4. Open evince with a document (i.e., try the link provided above). It SHOULD crash.
