Subject: [PATCH] Fail parsing early on if encoding conversion failed
To: libvir-list@redhat.com
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.
