[Message part 1 (text/plain, inline)]

Hello Guix!

It appears that our python is incorrectly compiled or compiled with 
missing component. Due to this, OMEMO plugin in gajim does not work.

Here is the output for `gajim -l gajim.p.omemo=DEBUG`:

*** START ***
Traceback (most recent call last):
  File 
"/gnu/store/5h0xfqysfddzc4283wcyr0j8jj2zaz9c-gajim-1.2.2/bin/..gajim-real-real",

    import re

line 143, in <module>
    class RegexFlag(enum.IntFlag):
AttributeError: module 'enum' has no attribute 'IntFlag'
*** END ***

Also, I am flagging this issue as 'important' as it affects 
security/privacy of messaging in gajim application.

Regards,
RG.

It's not a problem with Python but with Gaijim or one of its dependency:

--8<---------------cut here---------------start------------->8---
$ guix environment --pure --ad-hoc python -- python3 -c 'import enum;print(enum.IntFlag)'
<enum 'IntFlag'>
--8<---------------cut here---------------end--------------->8---

Summarily searching on the interwebs it seems that python-enum34 may be
at cause.  You should look if it's being propagated by any of the
dependencies of gajim or gajim-omemo, and probably get rid of those as
this package exists for backward compatibility for Python versions older
than our 3.8.2 on master.

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

Oh, I sent an email to debbugs-control long ago to close this bug. It 
seems like the email didn't go through. I'll retry.

After discussing with cbaines in IRC, the issue was resolved. It was 
python2-enum in the environment that was messing with python-enum.

Regards,
RG.

It seems your message hadn't reached Debbugs.

No worries, I'm closing it now, by replying in Cc: to
44782-done <at> debbugs.gnu.org.

Thanks for the report!
