Now, I normally use stable, that is, 16.09.1772.6e17350. When trying to activate the OMEMO plugin, it complains that I have to install python-axolotl. I tried the following in my ~/.nixpkgs/config.nix:

In unstable you should get by default all dependencies required for Omemo:

https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/networking/instant-messengers/gajim/default.nix#L13

These are the packages added to make it working:

You can actually remove your own override.
