I think it's in /tmp/last-installer-error, isn't it?

How would that help?  The default is only used if NAME is missing in the
constructor call, right?  Or is it also used if NAME is present but #f ?

Have you checked whether you can then still connect to that nameless Wifi?

(since apparently connman.scm passes service-path to connman, it should
be fine.  But still good to test it)

I think there are some "security" settings on Wifi routers that allow
you to hide the SSID or something, so I guess that's how this problem
sprung up.
