Reverting just that commit was verified to work.

Unity doesn't start (or starts and fails at the same time). No way to launch anything from there. I'm stuck. That's critical. ( I could finally create this bug report by SSHing into one of the machines and forwarding X. I'm not sure whether it may or may not influence the data attached to this bug report...)
