Hi all,
I have used the xAuth system to get myself this HTTP response:
HTTP/1.1 200 OK
(Clipped lots of other headers)
oauth_token=17396968-

I spotted a source in your Base String. You don't need to send that one.
As long as you send these properly, it will work :
oauth_consumer_key wd0XX6G9m9O7OYRg
oauth_nonce e68644aad6fd745d5022
oauth_signature_method HMAC-SHA1
oauth_timestamp 1283866974
oauth_token
