This problem is this call in locale_config, which rage depends on for localizations. rage works in every other context but this check on my machine.

Thanks for reporting. I can confirm that this happens on aarch64-darwin and x86_64-darwin.

Unfortunately, I cannot really reproduce this bug outside a Nix build. The same calls issued in decrypt-with-age seem to work fine when using rage from latest nixpkgs in a regular shell session (on aarch64-darwin):

# nix --version
nix (Nix) 2.5.1
# nix shell 'github:nixos/nixpkgs/43cba143c05a491265b6f7da81ce7d9284158c31#rage'
# rage --version
rage 0.7.1
# rage -i example/keys/id_ed25519 -d example/github-runner.token.age
wurzelpfropf!
# rage -i example/keys/id_ed25519 -d example/root.passwd.age

Is your sandbox on? If so, can you reproduce this issue with it disabled?

[Vincent Haupert]

Good one: the error doesn't occur with --no-sandbox.
