Bug#565992: libwebkit-1.0-2: invalid element name error for http XHTML pages declared as iso-8859-1

[Vincent Lefevre]

Package: libwebkit-1.0-2
Version: 1.1.18-1
Severity: important

Webkit-based browsers (tested with midori and GtkLauncher) cannot
render my web site just because it uses iso-8859-1 encoding, i.e.
pages start with:

<?xml version="1.0" encoding="iso-8859-1"?>

Testcase: http://www.vinc17.net/test/url-accented-latin1.html
(note: the contents don't matter, this was just for another test).

I get the following error:

  This page contains the following errors:
  error on line 2 at column 2: StartTag: invalid element name
  Below is a rendering of the page up to the first error.

Note that only pages served by http are affected. I do not get any
error with "file://...".

There's no problem with utf-8, e.g. on
  http://www.vinc17.net/test/url-accented-utf8.html

Note: my web site uses content negociation, so that pages can be
served either as application/xhtml+xml (preferred) or as text/html.
I don't know what webkit requests, but in the later case, the
Content-Type is correct anyway:

$ wget -S http://www.vinc17.net/test/url-accented-latin1.html
[...]
  Content-Type: text/html; charset=iso-8859-1
