The objects returned by that call are owned by libnm-glib, so you only
need to unreference them if you ever explicitly called g_object_ref() on
them at any point.

When you see the problem, does the #  of access points returned by
nm_device_wifi_get_access_points() correspond to the output of
'nm-tool'?  I took a quick look at the code and it seems to be doing the
right thing, provided that NetworkManager is correctly aging the access
points and sending the AccessPointRemoved signal when they are removed
from NM's internal list.
