My guess is a scriptlet is failing - quite possibly because an SELinux 
chcon command fails in those conditions. They probably need to change 
the chcon portion of the scriptlet to add a ||: after the command so it 
doesn't bomb out.

Someone should take a look at the spec file, add the ||: after the chcon 
(or whatever it might be) and if it allow the package to update, file a 
bug report upstream so it gets fixed in rhel svn.
