This is indeed happening with Android 4.4, but in your case you're not correctly executing the test case (you should run the android executable from the android container).

To run this test case specifically:
rsalveti@evasys:~$ adb shell
root@ubuntu-phablet:/# lxc-console -nandroid -t0

Connected to tty 0
Type <Ctrl+a q> to exit the console, <Ctrl+a Ctrl+a> to enter Ctrl+a itself
130|root@flo:/ # direct_camera_test
....

It crashes with a segfault because it's trying to render using framebuffer, instead of hwcomposer.
