Comment # 9 on bug 1088463 from Petr Gajdos

Johannes,

I had a very nice weekend and I hope you too.

Thanks for your analysis.

Helvetica font family is hardcoded on several places in ImageMagick. For
example, it is requesting 'helvetica' shape alternative as a fallback in
MagickCore/annotate.c:

[...]
  if (draw_info->font == (char *) NULL)
    args.pathname=ConstantString("helvetica");
  else
[...]

This is causing the exception during run of 4 referenced demo files in comment
1:

Caught exception: button: unable to read font `helvetica' @
error/annotate.c/RenderFreetype/1432

So I think that not only tests of ImageMagick will be affected by removal of
ghostscript-fonts. Question is why FT_Open_Face() is failing.
