A better way of writing this is:
try:
    import dbus.glib
except ImportError:
    have_nm = False
else:
    bus = dbus.SystemBus()
    proxy_obj = bus.get_object('org.freedesktop.NetworkManager', 
        '/org/freedesktop/NetworkManager')
    dbus_iface = dbus.Interface(proxy_obj, 'org.freedesktop.NetworkManager')
    have_nm = True

this way, only the import statements are in the 'except ImportError' guard.
