Steps to reproduce: 1. Start gnucash from a terminal ($ gnucash) 2. Press CTRL+H to open the "GnuCash Tutorial and Concepts Guide" 3. Observe the following is written to the terminal: /usr/share/gnome/help/gnucash-guide/C/ch_basics.xml:1508: namespace error : Namespace prefix xi on include is not defined <xi:include href="ch_accts.xml" /> ^ /usr/share/gnome/help/gnucash-guide/C/ch_basics.xml:1509: namespace error : Namespace prefix xi on include is not defined <xi:include href="ch_txns.xml" /> ^ $ lsb_release -a No LSB modules are available.

Interesting… We use https://www.w3.org/TR/xinclude-11/ since years. It is usually part of libxml2. Did debian split it in subpackages?
@fellen, The only answer to https://stackoverflow.com/questions/14542030/namespace-for-xinclude-included-elements claims that namespace scope does *not* reach into xincluded files. If that's correct the xmlns:xi attribute on <book> in gnucash-guide.xml isn't sufficient for the xincludes in ch_basics.xml; the latter needs its own xmlns:xi attribute on its <chapter> element.
Right, it was broken in commit 7a37189. Fixed in commit 843cc22.
