What follows is an Apache FOP bug (triggered by something in some of
your DocBook documents).
This FOP bug is not caused by our product, XMLmind XML Editor.
Therefore, we don't see how we could help.

PS: Googling
nullpointerexception
org.apache.fop.layoutmgr.inline.InlineStackingLayoutManager.getChangedKnuthElements(InlineStackingLayoutManager.java
pointed me to:
https://issues.apache.org/bugzilla/show_bug.cgi?id=48765
In a nutshell, it seems that passing XSLT stylesheet parameter
hyphenate=0
to the DocBook stylesheets is a workaround for this FOP bug.
If my memory serves me well, I've already seen this FOP bug before and I
thought that it was fixed in FOP 1.1 (the version included in XMLmind
XML Editor). It seems that this is not really the case.

So I got past the last issue. You were correct - I was trying to
convert a DocBook 5 document but using the incorrect module.
But now I'm getting a different message on *some* documents but not others:
[proj]$ ../xxe-pro-5_9_0/bin/xxetool convert db5.toPSFile

If I do this in the GUI, I get some more information:
