Switching nixos.org from 32-bit to 64-bit didn't change anything [1].  However,
I finally did find the cause: the Zabbix installation on the same machine set
the PHP configuration option "mbstring.func_overload" to 2, causing the
semantics of string functions to change globally, i.e. for Mediawiki as well.
Such a wonderful language...

Anyway, it should be fixed now.

[1] Fortunately this experiment didn't take long.  I just changed the
nixpkgs.system option in configuration.nix from "i686-linux" to "x86_64-linux"
and ran "nixos-rebuild boot".  Admittedly that only worked because distributed
builds are enabled on that machine :-)
