Messages getting lost
It seems somehow that messages get lost under certain circumstances. They appear in the XML log, but neither in the chat window or in the log.
In my particular case, it was the following XML that wasn't handled by Gajim and only showed up in the XML console:
\<message from='edtech@manga-france.fr/Ubuntu' to='test@webkeks.org' type='chat' id='215'>
\<body>sorry, phone ^^\</body>
\<active xmlns='http://jabber.org/protocol/chatstates'/>
\</message>
(It happened when we were testing some E2E stuff)
Messages getting lost is really the worst bug we can have. It's hard to reproduce, but we REALLY need to fix that before 0.12.
