+Subject: [PATCH] Fail parsing early on if encoding conversion failed
+
+For https://bugzilla.gnome.org/show_bug.cgi?id=751631
+
+If we fail conversing the current input stream while
+processing the encoding declaration of the XMLDecl
+then it's safer to just abort there and not try to
+report further errors.
+
+Upstream-Status: Backport
+
+CVE: CVE-2015-8317
