Differences between our html (bottom) and the html of the Help Content(top)

In the Acceleo project, we have the documentation in html integrated in the help.
The page "user guide" in our documentation works on some specific OS/Browser and it stays as a blank page on others.

You can see the page here: http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse.acceleo.doc/doc/html/acceleo_userguide.html

It works on:
- Mac OS X 10.6, Firefox as the default browser (Eclipse 3.6.1 and 3.6.2)
- Ubuntu 9.10, Firefox as the default browser (Eclipse 3.6.1)

Yet if fails on:
- Mac OS X 10.6, Chrome as the default browser (Eclipse 3.6.1 and 3.6.2)
- Windows 7, Internet Explorer, (Eclipse 3.6.0 and Eclipse 3.6.1)

We tried to extract the page from our documentation and the page works in all our environments. But when we try to see the same page from the Eclipse Help Content in the system browser it does not work anymore on the OS/Borwser that I mentioned previously.

The Webkit debugger finds some errors in the html produce by the help content that are not in our html file. It seems that those errors create a html file that cannot be read by Chrome/Internet Explorer.

It looks as though the XHTML transform is collapsing the <title> tag. The original page contains this html

<title></title>

which gets collapsed to <title/> by the help system, and this confuses some browsers.

An empty title is legal but not recommended since the <title> is used in search results. I think that if you give the page a title it will display correctly.

This is a bug in the help system but if my analysis is correct you will not see it if you give each page a title.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
