Actually, I can't seem to reproduce, using:

guix environment --pure --ad-hoc gajim gajim-omemo -- gajim -l
gajim.p.omemo=DEBUG

Then I tried signing up with some random account, enabled the plugin and
I could see:

12/28/20 23:28:16 (I) gajim.p.omemo              ($some-server) Generating OMEMO keys
12/28/20 23:28:21 (I) gajim.p.omemo              ($some-server) Our device id: 1816266738
12/28/20 23:28:21 (I) gajim.p.omemo              ($some-server) 100 PreKeys available

It seems like you may have 'pip3 install enum34' or have other things in
your environment that cause the issue?

If you can't reproduce in a clean environment, let's close it.

Thanks,

Maxim
