Public bug reported:
When I connect to a serve here at work I get kicked of after some random
time. It happenens even if something is going on in the session, so it
can't be some timeout.
I have seen the same thing happen on different servers using differen
clients. One common factor is that they all run ubuntu 10.10
A session disconnection looks like this :
