sleekxmpp 1.3.2
An upgrade of pyasn1 from 0.3.6 => 0.4.2 and pyasn1-modules from 0.1.5 => 0.2.1 on Arch Linux seems to break sleekxmpp with the following error.

After downgrading back to pyasn1 0.3.6 and pyasn1-modules 0.1.5 sleekxmpp works fine.

The above version fix workaround doesn't work for me with a valid Let's Encrypt certificate:
