    I DID Google dbus and it came up with many but one was interesting 
to me because it was another user having trouble with SELinux and he 
found the same problem I have. He said the problem in dbus was fixed in 
FC6 but is again a problem in F7.

    Now. Due to the problem with dbus I can't use SELinux because it 
uses dbus and has a problem with that. So your wrong with thinking 
SELinux does not use dbus, It certainly does and that I can prove.
