What happens: Whenever I run wine, the following messages get printed several times: Fontconfig error: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 70: non-double matrix element Fontconfig error: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 70: non-double matrix element Fontconfig warning: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 78: saw unknown, expected number I'm using media-libs/fontconfig-2.10.92 and app-emulation/wine-1.6. It can probably be reproduced by running some other kinds of applications (probably Steam too). There is a related bug in Arch Linux: https://bugs.archlinux.org/task/35039 According to that bug, it is most likely a misconfigured file from upstream.
https://bugs.freedesktop.org/show_bug.cgi?id=70258 upstream says it's a problem of programs linked to older fontconfig. In my case this is the case with skype, is it just a matter of updating app-emulation/emul-linux-x86-xlibs? On my system I have /usr/lib32/libfontconfig.so.1.4.4 and /usr/lib64/libfontconfig.so.1.7.0
I get the same errors with acroread-9.5.5. Doing an ldd on the acroread binary, it is linking to /usr/lib32/libfontconfig.so.1.4.4, which is owned by emul-linux-x86-xlibs-20130224. (wine and skype also depend on emul-linux-x86-xlibs so they are probably affected in the same way.) I wonder if this is from an older version of fontconfig, and thus causing the problem? I'll try to upgrade emul-linux-x86-xlibs to the ~amd64 version, but remembering the last time I played with that library, it is so linked to other emul-linux packages that I don't think I'll be able to upgrade just that one, and I'm not sure I want to play with all of them.
This was an issue with emul-linux-x86-xlibs which have been masked for removal.
