kblueplugd crashed with NameError in <module>()

Binary package hint: kdebluetooth

Very strange NameError in kblueplugd. My knowledge of python tells me this should not happen.

try:
        manager = dbus.Interface(bus.get_object('org.bluez', '/org/bluez'), 'org.bluez.Manager')
except:
        print "Unable to connect to bluez."
        exit

if len(manager.ListAdapters()):
^^^^^^^^^^^^^
    NameError here

        print "# of devices at startup:", len(manager.ListAdapters())
        distutils.spawn.spawn(kbtcmd)
else:
        print "No BT device found"
