Comment 6 for bug 1389355

Did you actually boot with systemd as PID1? Note that this isn't supported in Ubuntu 14.10 (only upstart). On current vivid, running "journalctl" under upstart just exits cleanly with 1. Can you reproduce this crash easily, i. e. does it still happen on your system if you run journalctl? (the stack trace isn't very helpful, I'm afraid).
