Terminal tab freezes when the SSH connection is closed unexpectedly
There seems to be an issue when connecting to another machine via SSH and the connection is terminated by the server side (for example, because of a timeout). The flow does not return correctly and the user cannot run any more command in the current tab and the only chance is to manually closing the tab from by pressing on the X.

this happens as well for other terminal apps (doesn't matter which desktop environment we are in) I think it's more an openssh-client issue, which not terminating when there is a long timeout or no timeout being set.
For the record I never had such problems on elementaryOS Luna. At that time when the connection was broken the prompt would return and I could easily start a new connection.
