Summary:

SELinux is preventing polkit-gnome-au "getsched" access on <Unknown>.

Detailed Description:

SELinux denied access requested by polkit-gnome-au. It is not expected that this
access is required by polkit-gnome-au and this access may signal an intrusion
attempt. It is also possible that the specific version or configuration of the
application is causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug
report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.
