Bug#909841: fc-cache: failed to write cache

[Holger Schröder]

There's something wrong with the last update to 2.13.1-1 anyway. I 
currently have 14350 files under /var/cache/fontconfig = 7.5 GB. And it 
is getting more and more.  Deleting the files doesn't help either, the 
propagation starts all over again.

Greetings
