When installing transmission-daemon from APT on a Jessie/Sid with
systemd enabled, dpkg fails with:

systemctl status transmission-daemon.service:
ExecStart=/usr/bin/transmission-daemon -f --log-error (code=killed, signal=SEGV)
process exited, code=killed, status=11/SEGV
systemd[1]: Failed to start Transmission BitTorrent Daemon.
systemd[1]: Unit transmission-daemon.service entered failed state.

Solution is to add path to configuration directory “-g /etc/transmission-daemon” into following file:

/lib/systemd/system/transmission-daemon.service

ExecStart=/usr/bin/transmission-daemon -f --log-error -g /etc/transmission-daemon
