Emitting a signal with a tuple

[Luigi Paioro]

Hello!

I have an object which emits a signal. The signal is a method with 1 
argument which is a tuple (Python). When it emits the signal I get this 
error:

   File "/usr/lib/python2.4/site-packages/dbus/proxies.py", line 48, in 
__call__
     reply_message = self._connection.send_with_reply_and_block(message, -1)
   File "dbus_bindings.pyx", line 350, in 
dbus_bindings.Connection.send_with_reply_and_block
dbus_bindings.DBusException: Argument of unknown type '<type 'unicode'>'

While, if I emit a simple string, it runs.

My dbus Python binding version is 0.42.0... is it possible that that 
version doesn't support the translation of tuple into dbus.Struct 
(STRUCT type)?

Can you help me?

Thanks.

Luigi
