Something is removing the cgroup before we can add the process to the cgroup. One way to track this down might be to use Martin Pitt's fatrace tool to check which process is removing the cgroup ultimately.

If you disable it, everything works as expected? I'd recommend reporting it to the abrt-ccpp people. I don't think this is related to how systemd starts/stops it. The developers of it should probably know more. Btw., I'm not entirely sure what that service does, so you might wanna show us the service file. It's not part of the systemd tarball, as far as I see.
