I realized that Jeff may very well be on a holiday so I took a closer
look and this does appear to be the/a problem. If you try to "cat
/sys/fs/selinux/ss/sidtab_hash_stats" on a system where the policy
hasn't been loaded it blows up in a bad way. I'll write up a fix
right now and post it as soon as I've verified it fixes the problem.
