Description of problem:
I am running with SELINUX=disabled in /etc/sysconfig/selinux
ls -Z says that I need a Selinux kernel
getenforce says disabled

so far nothing strange. However when I run up2date and it actually does
something, (i.e., I have something to install) I get about a thousand
invalid context warnings from /etc/security/selinux/file_contexts. 

Typical messages are 
/etc/security/selinux/file_contexts:  invalid context
root:object_r:staff_home_xauth_t on line number 1750
/etc/security/selinux/file_contexts:  invalid context
system_u:object_r:default_context_t on line number 1751

On the fedora-test-list I was told

RPM is checking to see the contents of
/etc/security/selinux/file_context for
each file installed, and the kernel is telling rpm it has no idea what 
it is talking about and rpm is reporting this as an error (Warning
actually).  So RPM should be doing a check to is_selinux_enabled()
before trying to assign context.

Version-Release number of selected component (if applicable):
rpm-4.3.1-0.1

How reproducible:
Always

Steps to Reproduce:
1.Make sure that SELinux is disabled
2.Login as root
3.run up2date when there is something to update
    

Actual Results:  up2date ran and installed the new packages but gave
about a thousand warning messages

Expected Results:  install packages without warning messages

Additional info:

I am using kernel-2.6.4-1.305 and policy-1.9.2-12
