TypeError in register(): on_fail() takes exactly 1 argument (2 given)

[Andreas Hasenack]

Triggered a registration error by trying to register with an LDS server that isn't up. The broker failed after 30s, which is expected:

2012-03-12 10:58:03,845 ERROR [PoolThread-twisted.internet.reactor-1] Error contacting the server at https://ec2-107-22-16-212.compute-1.amazonaws.com/message-system.

But then apport showed up saying ubuntu had a problem, and details show that landscape-client-settings-ui crashed:
