landscape-client-settings-ui crashes if System Policy password prompt remains unanswered for about 25s

[Andreas Hasenack]

To reproduce, launch landscape-client-settings-ui and do nothing for about 30s:

$ time landscape-client-settings-ui

The password prompt remains on screen, but it doesn't call landscape-client-settings-ui after that crash even if the password is correctly entered then.
