And after a reboot, same icon, same 'Network Management disabled' message and 
same dialog that doesn't allow WPA-PSK.  That dialog looks a lot like the one 
we used to have 2-3 years ago :-(

wlassistant tells me

==>stderr: Failed to connect to wpa_supplicant - wpa_ctrl_open: No such file 
or directory
Using wpa_supplicant driver: wext
WPA client started. Waiting for status...
==>stderr: Failed to connect to wpa_supplicant - wpa_ctrl_open: No such file 
or directory
CONNECTION FAILED.
disconnect: /sbin/iwconfig eth0 mode managed key off ap off essid off
