Same thing here, with mozilla seamonkey, particularly when restarting 
seamonkey.
I think that it is due to not confirming that the first copy was 
properly received.  So a second copy is sent, to assure that you do have 
a good copy of the message.
The alternative would be missing a message from time to time.
So I don't think that it is really a problem.

BTW, I sometimes have a similar problem sending SMS messages on my 
mobile phone.  It says that it is still sending a message, evidently 
because it didn't receive the confirmation.  (All the usual signs except 
the beep at the end.)  So to ensure that it is sent, I save the message, 
turn off/on my phone, and resend.  Sometimes (but maybe not always) my 
correspondant receives 2 identical messages.
