Description of problem:
Some setroubleshoot reports contain references to None.  It looks like the
Python parsing code isn't getting something it's expecting.

SELinux is preventing /usr/sbin/showmount (automount_t) "getattr" access to None
(automount_t).

Version-Release number of selected component (if applicable):
setroubleshoot-0.41-1

Actual results:
"SELinux is preventing /usr/sbin/showmount (automount_t) "getattr" access to
None (automount_t).

Sometimes labeling problems can cause SELinux denials. You could try to restore
the default system file context for None, restorecon -v $TARGETPATH. There is
currently no automatic way to allow this access. Instead, you can generate a
local policy module to allow this access - see FAQ - or you can disable SELinux
protection entirely for the application. Disabling SELinux protection is not
recommended. Please file a bug report against this package. Changing the
"automount_disable_trans" boolean to true will disable SELinux protection this
application: "setsebool -P automount_disable_trans=1."

Seeing similar problems with:
"SELinux is preventing /sbin/busybox (dhcpc_t) "setuid" access to None (dhcpc_t)."

Should I try and dig out the actual AVC denials?  (maybe the tool should have a
"show me the raw message" option for this?)
