Comment 50 for bug 94048

I did have a similar problem, turn out to me a fontproblem, fc-cache did'nt update the fontcache
because of a timestamp issue, try to touch the font dirs, and run fc-cache again.

sudo fc-cache -fv 2>&1 | grep failed | cut -f1 -d":" | xargs -i sudo touch {} && sudo fc-cache -fv
