hm, but is home/ce/cache a path where there are fonts to be found? 
something sets that path to be a fully recursive font dir

can you set OSFONTDIR to '/usr/share/fonts'

(personally i never use system fonts, i always put copies in 
texmf-fonts/fonts/data becasue system fonts can change or disappear)

well, it's not entirely clear what generates the permission denied; i 
can check for the home/ce being readable but doing that for every 
regular file below that would add lots of slow checks and i'm not even 
sure if it would fix it; i can try to check nested dirs but that then 
also obscures possible issues
