The OP did indicate that F10 was the platform:

so I would agree here that SELinux is almost certainly the culprit as  
it does control relocation.

If you have the SE Troubleshoot daemon running, you should get a

Typically, if you click on this, it will bring up a dialog window that  
will have some specific suggestions for resolving the problem. You can  
see some visual examples here:
