Downgrading fontconfig doesn't work, so it's probably a cairo problem, although I can't test it because the soname changed recently.
Downgrading to something pre 2.6.9x should have worked, this is caused by 9a7c41b29f33dcd3cf7b3a422b1e46e3b88e11fe [fcmatch] Move FcFontSetMatch() functionality into FcFontSetMatchInternal() in http://cgit.freedesktop.org/~behdad/fontconfig/ In its previous version FcFontMatch never called FcFontRenderPrepare if there was no font available (like in mock chroot)
Adding this line work-around the problem for now: BuildRequires: liberation-sans-fonts fc-match crashes as well when no fonts are installed.
Bastien, cairo .soname changed?
