Segmentation fault at the end of splay

Bug detailed descriptions:
--------------------------

splay from helix-dbus-server_0.242-beta2_lpia.deb has error on free in
CUnixPref::~CUnixPref().

Reproduce steps:
----------------

1. Install Moblin: http://umd-repo.jf.intel.com/repos/users/inuka/Beta6_install.img and
Helix: http://umd-build.jf.intel.com/build-results-proprietary/helix-dbus-server-
atlas/lpia/helix-dbus-server_0.242-beta2_lpia.deb .

2. Download B-V-MPEG_PS_NTSC-AC3-8.mpg from ftp://xwu2-
image.jf.intel.com/restricted/dm/menlow/tiny-
test-set/

3. Run "valgrind --tool=memcheck --leak-check=no ./splay
/root/tv/tiny-test-set/B-V-MPEG_PS_NTSC-AC3-8.mpg >& ~/log.txt"

Current result:
----------------

# cat ~/log.txt

it is invalid because either helix-dbus-server or moblin-media won’t depend on
splay. Splay is just a sample player. Anyway, we can report it back to helix
community.

Please, report this issue back to Helix community.

Halley, could you add helix bug link to this bug, so we know where is it?
Thanks.
