mcstrans-0.3.1-4.el6.x86_64

How reproducible:
always

Steps to Reproduce:
0) get a RHEL-6.8 machine with active targeted policy
1) use /etc/selinux/targeted/secolor.conf file with following content:
color black  = #000000
color green  = #008000
color yellow = #ffff00
color blue   = #0000ff
color white  = #ffffff
color red    = #ff0000
color orange = #ffa500
color tan    = #d2b48c
user unconfined_u = #ff0000 green
role unconfined_r = red #ffffff
type unconfined_t = red orange
user user_u       = black green
role user_r       = white black
type user_t       = tan red
user xguest_u     = black yellow
role xguest_r     = black red
type xguest_t     = black green
user sysadm_u     = white black
range s0:c0.c1023 = black white
user *            = black white
role *            = black white
type *            = black white
2) start mcstransd
3) run following command as common user or as root:
echo -en 'import selinux\nselinux.selinux_raw_context_to_color("user_u:user_r:")\n' | python
4) check the status of mcstrans daemon

Actual results:
 * it segfaulted

Expected results:
 * it's running
