As I said already, 14.10 has another problem.
Go to Network Settings or Network Connections, edit the Eduroam connection, and go to the WiFi Security tab.
Here set the authentication type to Protected EAP instead of the default Tunneled TLS which is wrong for eduroam, at least on my university.
It is unrelated to this bug so feel free to open a new bug for it, if you did not need to do this in past releases of Ubuntu.
