OK, seems to be related to dbus running inside container. Here is
a script to reproduce the bug:

----script-to-trigger-above-bug-------
#!/bin/sh

set -e

cat >cr1.config <<EOF
lxc.tty = 0
lxc.utsname = cr1
lxc.cgroup.memory.limit_in_bytes = 536870912
lxc.cgroup.memory.memsw.limit_in_bytes = 1073741824
lxc.cgroup.cpu.shares = 1024
lxc.console = none
lxc.cgroup.devices.deny = c 5:1 rwm
lxc.seccomp = 
lxc.network.type = empty
EOF

# create vidid with dbus
lxc-create -n cr1 -f cr1.config -t ubuntu -- -r vivid --packages dbus

lxc-start -n cr1

sleep 5

rm -rf /tmp/cr1
lxc-checkpoint -v -D /tmp/cr1 -n cr1

echo "CHECKPOINT OK"
