Interesting issue.  This is an inconsistency in the API which was
exposed by GObject Introspection bindings, since C doesn't have runtime
type safety and doesn't care when we try to do what you're doing.  We
have 3 different types for the SSID in libnm-util and libnm-glib, and
even though they are all the same underneath (GByteArray) the GOI
bindings cannot convert seamlessly between them.

I've spent a while trying to figure out how to work around this, but I
think we'll have to add some API to libnm-glib or libnm-util to convert
between the properties :(
