I found it happens less often with shepherd-0.8. What version are you
running? Also possibly related, do you have mismatched versions of guile
between guix packages and your distro's native packages?

I've also sometimes found shepherd to crash when I add a service where
the start command is "wrong", as though the error were so bad that
shepherd says "Nope! That's it! I quit!"

I'd suggest looking at .config/shepherd/shepherd.log but it's rather
sparse. Still, it might have something useful.
