[Pkg-giraffe-maintainers] Bug#1017035: kopano-presence: please migrate from sleekxmpp to slixmpp

[Martin]

Package: kopano-presence
Version: 8.7.0-7.1
Severity: important
Tags: patch

Dears, kopano-presence depends on python3-sleekxmpp, which is deprecated
in favour of python3-slixmpp. Upstream homepage says:

>  This repository has been archived by the owner. It is now read-only.

And:

> SleekXMPP is deprecated in favor of Slixmpp, a fork which takes full
> advantage of Python 3 and asyncio.

I'll ask for removal of sleekxmpp from both testing and unstable soon,
so please make sure, that kopano-presence gets ported to slixmpp, which
in this specific case should be as simple as

$ sed -i 's/sleekxmpp/slixmpp/g' debian/control \
    ECtools/presence/kopano_presence/plugin_xmpp.py

Thank you!
