Seg fault with a python analyzer

Hi,

This piece of python code is intended to print "Message received" everytime
a new alert is received by the Prelude Manager. It works ok, but when I send
a signal to it (e.g. SIGINT) in order to stop it, I get a segmentation
fault... Any idea where this could come from?

Thanks in advance,

Ben

    prelude.prelude_client_destroy(client,
prelude.PRELUDE_CLIENT_EXIT_STATUS_SUCCESS)
    print "Stop"
    sys.exit()

signal.signal(signal.SIGINT, correlator_stop)

prelude.prelude_init(1, ["PythonTest"])
client = prelude.prelude_client_new("PythonTest")

prelude.prelude_client_set_required_permission(client,
prelude.PRELUDE_CONNECTION_PERMISSION_IDMEF_READ|prelude.PRELUDE_CONNECTION_PERMISSION_IDMEF_WRITE
);

prelude.prelude_client_start(client);

pool = prelude.prelude_client_get_connection_pool(client)

while 1 :
    msg = prelude.prelude_connection_pool_recv(pool, -1)
    print "Message received"
