Key appearing twice in keyring and upload to keyserver problem

[Nicolas Duboc]

    Hi,

(Sorry in advance for the long post.)

 I have two questions which may be related.

 My keyring seems to include my own key twice :

----------------------------------------------------------

pub  1024D/F801A743 2002-10-01 Nicolas Duboc <nicolas at duboc.net>

----------------------------------------------------------

The second key correspond to a previous state of my key (before I added
the second encryption key 1CF0D39E).

Shouldn't the keyring merge these two keys ?
When I export my public key, the armored string seems to contain the two
key entries but including it to another keyring seems to merge them.

----------------------------------------------------------
nico at bilby:~$ gpg --import <duboc-key.gpg 
gpg: key F801A743: public key "Nicolas Duboc <nicolas at duboc.net>" imported
gpg: key F801A743: "Nicolas Duboc <nicolas at duboc.net>" 1 new signature
gpg: Total number processed: 2
gpg:               imported: 1
gpg:         new signatures: 1
----------------------------------------------------------

I managed to produce a correct armored exported key by importing it in
an empty keyring and exporting it again.

My second problem concerns upload to keyserver : when I try to upload my
key including the new encryption key to a key server, I get this error
message :
----------------------------------------------------------
Key block in add request contained no new
keys, userid's, or signatures.
Your key block contained 2 format errors,
which were treated as if the erroneous elements
hadn't been part of your submission.
The last error was on key 0x1c6ccd1c:
Key block corrupt: more than one signature on subkey
----------------------------------------------------------

I don't really understand the message.
May someone explain me what's wrong with my key ?

My pgp is available here : http://www.duboc.net/nicolas/duboc-key.gpg
(the one containing the two entries is here :

 Thanks in advance,
