Looks like something went screwy with SELinux.

Run this command as root:

	setenforce 0

and try re-starting messagebus and/or avahi:

	/sbin/service messagebus start
	/sbin/service avahi-daemon start


If the services now start up, it is definitely something to do with SELinux.


You can either reset all of the SELinux security labels:

	restorecon -Rv /

or if you are less concerned about the system's security features, you 
can set SELinux to permissive mode by editing /etc/sysconfig/selinux and 
changing
	SELINUX=enforcing
to
	SELINUX=permissive
