 After restarting NetworkManager (because it died after resume - a separate
 bug), I cannot connect to my AP anymore. On the Sugar side, there are no
 error messages - it just silently fails (without pulsing). In syslog,
 NetworkManager says:

 Restarting Sugar doesn't help; a reboot is required.

 The log for a successfull attempt differs after the "5 -> 6" state change
 and "Stage 2 of 5 (Device Configure) complete" (maybe because Sugar sent
 the required secrets?):
