UI lockups during network problems
Bug description
When there is a temporary network outage between gajim and the XMPP server, the UI completely locks up, and unfreezes only after the connectivity is restored. Network communication should probably be made more asynchronous from the GUI handling.
Steps to reproduce
Run gajim, log in to a remote XMPP server, open the chat window, pull the uplink plug from your router, and try to type something into the chat window.
