This was a common log entry in early FC5 systems. It's harmless but can 
tend to fill the log files. However, it indicates that you have not 
installed updates (specifically for selinux, probably not for anything 
else either) as the logging of these events was turned off in one of the 
updates.

It's conceivable that installing updated X packages might fix the 
problem you've been writing about.
