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
