docbase trouble

[debian-devel@liska.ath.cx (Olе Streicher)]

Hi everyone,

on my current package, lintian complains about

I: xpa-dev: possible-documentation-but-no-doc-base-registration

in the package directory, I have:

$ ls debian/xpa-dev/usr/share/doc/xpa-dev
acl.html             convert.html   info.html      server.html    xpa.pdf.gz
changelog.Debian.gz  copyright      intro.html     tcl.html       xt.html
changelog.gz         env.html       method.html    template.html
changelog.html.gz    examples.html  name.html      users.html
changes.html         help.html      oom.html       xpamb.html
client.html          inet.html      programs.html  xpans.html

and my xpa-dev.docbase says:

---------------8<------------------------
Document: xpa
Title: [...]
Section: [...]
Abstract:  [...]

Format: PDF
Files: /usr/share/doc/xpa-dev/xpa.pdf.gz

Format: HTML
Index: /usr/share/doc/xpa-dev/help.html
Files: /usr/share/doc/xpa-dev/*.html
---------------8<------------------------

I have two questions here:
1. Why does lintian complain? Both HTML and PDF are mentioned in the
docbase.

2. The changelog.html.gz was installed by dh_installchangelogs. However,
the file is referenced by help.html, so I would like to have it
uncompressed. Is there a way to instruct dh_installchangelog to keep it
uncompressed? 

Best
