Package: konqueror
Version: 4:3.2.1-1
While testing some updates to my website, I found that konqueror would
SEGV while viewing a certain page while displaying and undisplaying
images with CSS.
A short example of some code that causes konqueror to SEGV (the image
used/existance does not matter):
-----Example-----
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11-strict.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<style type="text/css">
body{float: left;}
ul li img{display: none;}
ul li:hover > img{display: inline; float: right;}
</style>
<title>An almost contentless website</title>
</head>
<body>
<ul>
<li>foo<img src="/usr/share/bmp/Skins/Default/main.bmp" alt="foo" />
</li>
</ul>
</body>
</html>
---End example---
