Description of problem:
As mentioned in https://bugzilla.redhat.com/beta/show_bug.cgi?id=149114#c10, since some RPM upgrades on Feb. 18, load_policy has been dumping core into
/etc/selinux/targeted/src/policy due to an assertion failure when I login from the console.  Logging in via ssh does not trigger the assertion failure.  The core file backtraces all look like this:

(gdb) bt
#0  0x006fe7a2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2
#1  0x0073e955 in raise () from /lib/tls/libc.so.6
#2  0x00740319 in abort () from /lib/tls/libc.so.6
#3  0x00737f41 in __assert_fail () from /lib/tls/libc.so.6
#4  0x004d3570 in security_get_boolean_names (names=0x0, len=0xbfe22bfc)
    at booleans.c:48
#5  0x08048bc9 in main (argc=2, argv=0xbfe22d04) at load_policy.c:96
#6  0x0072be33 in __libc_start_main () from /lib/tls/libc.so.6
#7  0x08048891 in _start ()

The failed assertion is "assert(selinux_mnt);".  GDB shows that selinux_mnt is NULL.  Note that, while I have all of the selinux packages installed, selinux is disabled at boot time.

Version-Release number of selected component (if applicable):
policycoreutils-1.18.1-2.9

How reproducible:
Always

Steps to Reproduce:
1. Login from the console
2.
3.
  

Actual Results:  A new core file appears in /etc/selinux/targeted/src/policy.

Expected Results:  Something like this ought to be syslogged instead of silently failing.  I didn't even know those core files were accumulating until I stumbled across them by accident.
