NM implements access point priority by a "last connected" metric, by
default trying the access point you last successfully connected to.
There is intentionally no "priority" field and users should not need to
manually re-order their connections.

It's a standard D-Bus interface that all the NetworkManager objects
implement.  It just allows the caller to grab properties off the object
using a defined mechanism.

This one is a bug, an object path of "/" should mean NULL.  I'll fix
this, an object path of "/" should _never_ leak out of libnm-glib.

This means that libnm-glib hasn't disposed of an access point that NM no
longer knows about.  I think what's happening here is that reference
counting in the calling program isn't quite correct, and the caller is
using the AP after it's supposed to be gone.

What sorts of things are you attempting to do here?  I assume you're
reading the properties off the AP, are you doing this when the AP
appears, in response to a signal from the libnm-glib
NMDevice80211Wireless object, or some other way?  Is your program
holding on to the AP after the signal saying the AP has disappeared
comes to your program?
