Those avcs suggest that you are using enableaudit.pp, as they would
normally be silenced by dontaudit rules.  Try running the program under
strace and checking the output to see precisely where it is failing.
One case where we get no auditing at all is the net_admin capability
check upon netlink recv; that will be fixed by a pending patch in the
audit tree.  Hopefully googleearth doesn't need that though ;)
