"restorecon" fixes the SELinux context of the file.  Most other forms of 
repair (short of removing and reinstalling the package) will not do 
that.  If the context is correct, you should not get the errors that you 
saw.

"restorecon -v" is instructive in telling you whether or not anything 
needed to be fixed.  "ls -lZ" will show you the context which is 
currently set.

Look in /var/log/audit/audit.log.  Specifically, watch for lines 
containing "AVC".
