Yes, I can connect to the server via telnet. Also TB log file shows it talked to the server.
Maybe that is the problem, that you do not even connect to the server and get the timeout. I used a nonexistent server now. I got timeout immediately and the progressbar still spinning.
Also notice there is another small progress bar in the bottom right corner of the compose window. So all those animations could be quite heavy, maybe they are redrawing too frequently. I can confirm this part of the bug.
