I dug some more. This is just getting better, look:
root@Delta:~# lsof /dev/urandom
lsof: WARNING: can't stat() fuse.gvfs-fuse-daemon file system
/home/gebruiker/.gvfs
Output information may be incomplete.

Charon is listed while having urandom opened! So I did a strace
(including forks this time!) to see what charon is actually doing, it
fails on this (I attached the full trace):
[pid 22519] open("/dev/urandom", O_RDONLY) = -1 EACCES (Permission
denied)
Which crazy since:
