Versions

• OS: Debian unstable
• Gajim version: HEAD
• GTK version: debian unstable
• Python-nbxmpp version: HEAD

I track gajim HEAD. Since a couple of weeks ago from time to time new messages from contacts are not reported in the UI. They can be seen if I close and reopen the chat window or if I disconnect and reconnect from the XMPP server.

I have noticed this trackback, which could be related:
