+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
