revoking a key using 'addrevoker'

Hash: RIPEMD160


after adding one of my keys as a deisgnated revoker, by using
the --edit-key 'name' command 
and 
'addrevoker'

and then   'save'

then,
upon editing the key, gnupg listed the added designated revoker
as being able to revoke the key.

then, when trying to send the updated key with the new revoker
to the keyserver, got the following error message:

"Sending key(s) 0x46D7F7C7 to server x-hkp://pgp.mit.edu ...

<title>Public Key Server -- Add</title><p>??<h1>Public Key

??<pre>??Key block in add request contained no new?keys,

.?Your key block contained 1 format errors,?which were treated

was on key 0x46d
7f7c7:?Key block corrupt: signature before userid?</pre>??gpg:
success sending t
o `pgp.mit.edu' (status=200)

Press any key to continue . . ."

neither the original key, nor the revoker key, have any photo-id
or any strange signatures or additional packets

is the new 'designated revoker key' not recognized by the
keyservers yet?
or is there a different way to try to upload a designated
revoker?

the version of gnupg used, is in the signing header.

tia,

vedaal
