question: why does nix-env --xml output differ from the --json output?

i think that this might be a bug.






nix-env -f '<nixpkgs>' -qa nix --out-path -A nix --xml

======================== summary ==========================
i've made many attempts of getting pyqwt to work and here is my newest fail:
SystemError: dynamic module not initialized properly

what i did was:
- now using qwt-5.2 bundled with pyqwt-5.2.0 implementation (for qwt)
- BUT i'm actually not using qw5 from the ${pkgs.qwt} directory but also the bundled one (don't ask, didn't get it working)

so this incarnation of Qwt.so seems to be working in regards to:
- readelf -s Qwt.so

i want to remove /dev/sdb from the Vg ve-daivb but it fails with the error below, so what do do now?

vgreduce ve-daivb /dev/sdb5
  Physical volume "/dev/sdb5" still in use


before vgreduce i did pvmove:

# pvmove /dev/sdb5 /dev/sda3
