Messages displayed twice

I’‘m not actually sure if this Smack’‘s fault or Spark’‘s, but if you create a Message object, don’‘t set the message type, and send it with XMPPConnection.sendPacket, Spark displays the message twice. The debugging console shows the message was received once, but two delivery notifications are returned. The ID’‘s of the notifications themselves are different, but both have the same ID for the message they’'re about.
