It's happening again for the ungrafting evaluation:

https://ci.guix.gnu.org/eval/45377/log/raw (sorry, this log is unhelpful)
https://ci.guix.gnu.org/eval/45377

And Chris Baines sees it in the Guix Data Service too:

http://data.guix.gnu.org/gnu/store/djr1vmhnl8z8yy4ymkszw5srvfmfv943-guile-3.0.7.drv

For now I'm doing something like `guix gc --clear-failures
/gnu/store/...-guile-3.0.7 && guix build /gnu/store/...-guile-3.0.7.drv`
in a loop on the Berlin server.
