    Fixed memory leaks in gpg decryption
    
    2012-09-12  Jeffrey Stedfast  <jeff xamarin com>
    
    	* gmime/gmime-gpg-context.c (gpg_ctx_parse_status): Unref the
    	certificate after adding it to the list (adding it to the list
    	refs it).
    
    	* gmime/gmime-multipart-encrypted.c
    	(g_mime_multipart_encrypted_decrypt): If the 'result' out param is
    	null, unref the GMimeDecryptResult to avoid leaking.
