With otto from lp:otto I can reproduce the problem with the command:
$ sudo ./bin/otto -d create -u lp1196518-$RANDOM ~/iso/ubuntu/saucy-desktop-amd64.iso
The write(fd, value, strlen(value)) in do_cgroup_set in cgroup.c fails with "Invalid Argument"
If the command is executed a second time with the same container name (replace $RANDOM by the number generated previoulsly), it works fine.
