trusted device checkbox unchecking => can't receive message and no roaster

[ahvauc-ux]

Describe the bug
when the checkbox "This is a trusted device" ain't checked, after logging in you can't communicate :
no roaster and no message at all will be received

To Reproduce
using such a webpage :

<script> converse.initialize({

    bosh_service_url: 'https://REPLACE_WITH_YOUR_DOMAIN/http-bind/',

    view_mode: 'fullscreen',

    authentication: 'login',

    clear_cache_on_logout: "true",

    allow_contact_removal: "false",

    allow_contact_requests: "false",

    clear_messages_on_reconnection: "true",

    message_archiving: "never",

    theme: "concord",


});

</script>

connect without unchecking "This is a trusted device" and everything works fine
connect after unchecking "This is a trusted device" no roaster and no message will be received

Expected behavior
the roaster should be displayed and the messages should be received regardless to that else what's the point ?

Environment (please complete the following information):
firefox
converse 12.0

when you check untrusted, the signal lib for omemo is not loaded, right?

so if you get encrypted messages you should not get anything, since you can't decrypt them

you tried with unencrypted messages too?
