It's fixed, livedocs complains about:
XML: 37:2 undefined entity Line: 37 is &contributors;
when you visit preface.html - and the link in bookinfo.html to the contributors is not there. Might be livedocs only - not sure.
I've traced this problem and I've found this is just a simple livedocs' problem.
As a well behaved livedocs' hacker, here is an explanantion of the problem: 1) the text is passed normally to bind_entities() 2) Then it asks for the entities to sqlite, using hard-coded 'where is_file=0'. The problem is that &contributors; is a file
The solution: remove the is_file=0 and allow entities to be files. Then check if the entity is a file (and if it is a file, call handle_include())
Probably I'll produce a patch to solve this little problem tomorrow.
Would be good. The previous error was also because of the missing entity I guess then. (It complained about malformed XML).
