+Subject: [PATCH] auth-digest: fix crash in
+ soup_auth_digest_get_protection_space()
+
+We need to validate the Domain parameter in the WWW-Authenticate header.
+
+Unfortunately this crash only occurs when listening on default ports 80
+and 443, so there's no good way to test for this. The test would require
+running as root.
+
+Fixes #440
+
+Conflict: Context Adaptation and g_uri_get_host (uri)->uri->host,g_uri_get_host (source_uri)->source_uri->host and Modify file path adaptation:libsoup/auth/soup-auth-digest.c->libsoup/soup-auth-digest.c
