OMEMO encryption with Gajim

[David Lecompte]

Hi everybody,

I use guix on trisquel 11. I have the following packages installed:

glibc-locales   2.35    out     
/gnu/store/03v1svhv6wj9pd6awpdi5zn4wd31b23f-glibc-locales-2.35
fontconfig      2.14.0  out     
/gnu/store/90jrg5z1ywz5hpwka832q0g4skbaa4dj-fontconfig-2.14.0
gajim-omemo     2.8.15  out     
/gnu/store/05vva4qcqgmmxclc2k41ypypisazvyxr-gajim-omemo-2.8.15
gajim           1.4.7   out     
/gnu/store/d42m4sjgx4m4wn1wysp65ckq62qllcwd-gajim-1.4.7
darktable       4.2.1   out     
/gnu/store/qc2a8q1jz4p174zc13y245x2r2vzg78y-darktable-4.2.1

On Wedesnday, omemo encryption was working find with gajim. Today (I did some 
updates but can't remember when exactly),
gajim does not allow omemo encryption anymore. In the plugin menu, I see omemo 
listed but I can't activate it and there
is an exclamation point next to it. When moving the pointer to it, there is a 
message "You are missing Python3-Axolotl
or use an outdate version".

I installed python3-axolotl from trisquel and python-axolotl from guix but it 
is still the same.

I am not sure what to do to make omemo encryption work again with gajim, any 
suggestion is appreciated.

David.
