Comment 5 for bug 157182

I have no trouble reproducing this on Hardy (8.04). I do not have 8.10 installed. The reproduce the problem, I use putty to connect over SSH to another host. On that host, I kill the sshd parent process and that causes a "Server unexpectedly closed network connection" dialog box to pop-up. The CPU usage on my machine immediately jumps to 30% user 70% system. The above entries explain in a general way the cause of the problem.

I borrowed an 8.10 system and the problem still occurs there.

As a work around I've been using a copy from the Putty Development tree. If you compare the ldd output, you can see the different gtk dependencies that the above poster pointed out.

% ldd /home/ota/down/putty.dev-snap.0.60-2008-06-24|grep gtk
 libgtk-x11-2.0.so.0 => /usr/lib/libgtk-x11-2.0.so.0 (0xb7bc7000)
% ldd /usr/bin/putty| grep gtk
 libgtk-1.2.so.0 => /usr/lib/libgtk-1.2.so.0 (0xb7dae000)
