Description of problem: I would like to suggest lowering the fontconfig priority of gnu-free-fonts from 67 to 69. Since it is a generic Unicode fallback font that would seem safer to avoid any potential conflicts with other specific native fonts. This is in the context of bug 868547 where we are trying now to install the GNU Free fonts as a default fallback font to provide better default glyph coverage for Fedora. I haven't seen any problems yet, but to be extra safe it it seemed recommended to lower the priority to 69 to avoid the Free fonts from potentially overriding other specific fonts. See the comments in bug 868547 for more details.
