soup_auth_authenticate

[Jari Urpalainen <jari urpalainen nokia com>]

Hi !

I was faced with a segfault in soup_auth_authenticate with digest auth 
(or actually in soup_auth_digest_compute_hex_urp()), when both username 
&& password are nulls.

So is this intentional in soup_auth_authenticate()  ? :
   g_return_if_fail (username != NULL || password == NULL);
instead of e.g.:
   g_return_if_fail (username != NULL && password != NULL);

br, Jari
