I can reproduce this with the current git HEAD (commit 0bfc54dedd309b3e265fb8d514e58ac1c67811af) and systemd-204 on Debian. This has also been reported as http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=731387 in Debian.

Steps to reproduce:
1) launch systemadm
2) sudo systemctl stop miredo.service

I have attached the output of “backtrace full” as an attachment.

systemadm is unmaintained. It should probably just be deleted.

Looking at its history, I doubt anybody will ever make it useful or even fix it.

Those issues seem to be fixed when recompiling with vala 0.22.
