I can confirm that downgrading fontconfig and libfontcofig1 solves the problem. Unfortunately, the 2.13.0 version is no more available in the archive, and previous versions are not compatible. So I had to recompile them myself. Here are the packages I just installed on my amd64 box:
<http://fly.isti.cnr.it/tmp/fontconfig_2.13.0-5_amd64.deb> <http://fly.isti.cnr.it/tmp/libfontconfig1_2.13.0-5_amd64.deb> You can download them, install them with $ sudo dpkg -i libfontconfig1_2.13.0-5_amd64.deb fontconfig_2.13.0-5_amd64.deb and prevent upgrading them with $ sudo aptitude hold fontconfig libfontconfig1 until this bug is solved -- Francesco Potortì (ricercatore) Voice: +39.050.621.3058 ISTI - Area della ricerca CNR Mobile: +39.348.8283.107 via G.
