I am on Arch. I have insync-3.9.10.60041-1 from AUR. This only happens on my systemd user service. Running insync manually works fine. I enabled it using systemctl –user enable insync as per docs. When I log in and type journalctl –user -fu insync, I get this:
May 25 11:12:54 desk systemd[1134]: Starting Insync...
May 25 11:12:55 desk systemd[1134]: Finished Insync.
May 25 11:12:55 desk systemd-coredump[1191]: [🡕] Process 1187 (insync) of user 1000 dumped core.
