ERROR:dbus.connection:Exception in handler for D-Bus signal:
Traceback (most recent call last):
  File "/usr/lib64/python2.6/site-packages/dbus/connection.py", line 214, in maybe_handle_message
    self._handler(*args, **kwargs)
  File "/usr/share/wicd/gtk/gui.py", line 243, in handle_connection_results
