Description John Maguire 2005-12-08 16:41:24 UTC 
Version:           1.2 (using KDE KDE 3.5.0)
Installed from:    Gentoo Packages
Compiler:          3.3.6 (Gentoo 3.3.6, ssp-3.3.6-1.0, pie-8.7.8) 
OS:                Linux

An example feed that shows the behaviour: http://mostlyharmful.blogdns.com/atom/
If an article is loaded from this atom feed, html tags are visible.

The feed is definitely correct; Akregator has the wrong behaviour as it displays the html markup as text. eg. "<p>" rather than either ignoring it, or parsing the tag.
Atom validator results: http://feedvalidator.org/check.cgi?url=http%3A%2F%2Fmostlyharmful.blogdns.com%2Fatom%2F

In section 4.1.3.3 of the Atom spec (http://www.ietf.org/rfc/rfc4287.txt), it states that all html markup within <content type="html"> should be escaped and that the markup may be used by Atom processors.

fix atom:content parsing: Don't show tags when for Atom 1.0 feeds with escaped HTML in it
