Some comments that may help others work around this bug:
==================

I have an idea of how to do this easily in Pango.  Give it a try.  The
main limitation is that it only works for actual files on the filesystem.  But
you may be able to wire it up through ~/.gvfs filenames?

1. FcConfigCreate()
2. FcConfigAppFontAddFile()
3. pango_cairo_font_map_new_for_font_type()
4. Use that PangoFontMap to create your context, etc.
5. Every time you want to use Pango with that context, FcConfigSetCurrent the
above config.  Then reset it back to whatever it was before.

This way, Pango will only see that single font.
