Thank you for reporting this issue and helping to improve Ubuntu.

This bug was reported against the version of systemd in Ubuntu 16.10, which has reached End Of Life. As such, we will not be fixing bugs in this version of the package. If this problem is reproducible on later supported versions of Ubuntu, please open a new bug (preferably with a fresh backtrace and crashdump) against that version.
