unconfined_execmem_t transitions to unconfined_t

Running latest rawhide, targeted/enforcing.

Are there any issues allowing transition from 'unconfined_execmem_t'
to 'unconfined_t'?

/usr/bin/valgrind is 'unconfined_execmem_exec_t', so running
'valgrind system-config-users' or
'PYTHONPATH=/usr/share/system-config-users valgrind /usr/bin/python
/usr/share/system-config-users/system-config-users.py'

produces:

Summary
    SELinux is preventing userhelper (unconfined_execmem_t) "transition" to
    /usr/share/system-config-users/system-config-users (unconfined_t).

Detailed Description
    SELinux denied access requested by userhelper. It is not expected that this
    access is required by userhelper and this access may signal an intrusion
    attempt. It is also possible that the specific version or configuration of
    the application is causing it to require additional access.

Allowing Access
    You can generate a local policy module to allow this access - see
    http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 Or you can disable
    SELinux protection altogether. Disabling SELinux protection is not
    recommended. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi
    against this package.
