I just tried to replicate this and restarted the guix-publish daemon on my machine a couple of times and no crash. Restarting the guix-daemon also didn't make my machine crash. I'm closing this bug, will revisit if it happens again. -- Efraim Flashner אפרים פלשנר GPG key = A28B F40C 3E55 1372 662D 14F7 41AA E7DC CA3D 8351 Confidentiality cannot be guaranteed on emails sent or received unencrypted
