Actually, even better yet, the new patched attached.

Otherwise:
# lxc-autostart -L
lxc-autostart: could not build log path
lxc-autostart: could not build log path
lxc-autostart: could not build log path

This bug was fixed in the package lxc - 1.0.0~beta4-0ubuntu2

---------------
lxc (1.0.0~beta4-0ubuntu2) trusty; urgency=medium

* debian/patches/dont_crash_log_init.patch: don't crash if no name is passed
to lxc_log_init(), such as is the case with lxc-autostart. (LP: #1277450)
