Comment 13 for bug 405188

I'm not able to reproduce this. I took your configuration file, adapted it to my hardware, set up all the needed fonts, and even went as far as using an external script to mount/dismount several times various drives and partitions and never had any crash.
The backtrace indicates that the crash is in a diskiograph call, which is then totally unrelated to fonts and the mounting of partitions, so I suspect that these aspects are not really related to your problem.
As a test, can you try to just use the diskiograph portions of your configuration file and see if that alone will cause any crash?
