+Subject: [PATCH] headers: Be more robust against invalid input when parsing
+ params
+
+If you pass invalid input to a function such as soup_header_parse_param_list_strict()
+it can cause an overflow if it decodes the input to UTF-8.
+
+This should never happen with valid UTF-8 input which libsoup's client API
+ensures, however it's server API does not currently.
