This comes from DerivationGoal() in 'nix/libstore/build.cc'.

I'm not sure what it's trying to do with `/' and I'm also not familiar
with that rather long function, so can you try attaching to the daemon
with strace [0] and letting us know exactly where it fails?

[0] Something like:
$ strace -f -p $(pgrep guix-daemon | head -n1)
