+Subject: [PATCH] Cleanup conditional section error handling
+
+For https://bugzilla.gnome.org/show_bug.cgi?id=744980
+
+The error handling of Conditional Section also need to be
+straightened as the structure of the document can't be
+guessed on a failure there and it's better to stop parsing
+as further errors are likely to be irrelevant.

+Upstream-Status: Backport
