It looks to me like a broken docbook installation on (one of?)
the CI machines. Note that the *first* complaint is

[19:23:20.590] file:///etc/xml/catalog:1: parser error : Document is empty

I suspect that the subsequent "failed to load external entity"
complaints happen because the XML processor doesn't find any DTD
objects in the local catalog, so it tries to go out to the net for
them, and is foiled by the --no-net switch we use.
