Thanks very much for your help.
I've finally figured out the cause: the nl80211 backend doesn't work
with a hidden SSID. The wext one does. Reconfiguring my router to
publish the SSID suddenly makes nl80211 work again.
I've contacted the wpa_supplicant list to see if this is expected
behaviour or a bug. Probably a bug, as it doesn't exit with an error
message but just fails to detect a network.
(and yes, I know that a non-published SSID can still be detected
reasonably easily with the right tools, ie doesn't add much to security).

Simon
