I can't reproduce this at commit 554cbe9. The only thing that comes to
mind is per-user configuration such as ~/.nixpkgs/config.nix, if
you're sharing that between your computers. If that's a possibility, I
guess you could try creating a new user and see if that user has the
same problem. Good luck :-)
