Hi Raghav,

I've found the reason for the test failure by using this patch:

 		g_assert (error == NULL);
 		server = soup_server_new (SOUP_SERVER_SERVER_HEADER, "simple-soup-httpd ",
 					  SOUP_SERVER_TLS_CERTIFICATE, cert,

Then I fixed the test failure by adding glib-networking (which is a GIO plugin).

I suspect that the tests won't work reliably because of the networking
involved (even when local)--but let's cross that bridge when we come to it.
