Bug#369963: konqueror: Reproducible crash on clicking text-entry-box on specific webpage (javascript?)

Package: konqueror
Version: 4:3.3.2-1sarge1
Severity: important

Hello Konqueror maintainers :-)

I am using konqueror on Debian Sarge with olvwm as window manager.

When visiting URL http://afroconnections.com/default2.asp
there are two text-entry boxes : 'username' and 'password',
when clicking on the username box, the text 'username' disappears, so a new value can be input ;
  this works OK.
when clicking on the 'password' box, konqueror crashes.

This only happens when javascript is enabled.
When preferences::enablejavascriptglobally is turned off,
 clicking pasword box results in needing to remove 'password' by manual editing,
 konqueror then does not crash, and i can log in to this site.
So this may be a javascript bug.
A toolbar button to turn javascript on/off would be an improvement.

The relevant part of the page source ( as far as i can see ) :

<TR><td align='right' valign='middle' height='60'>
	<table cellpadding='0' cellspacing='0' width='100%'>
	<script language='javascript'>
	<!--
	function blanklogin(){
		with (document.form1SP){
			if (Q_1.value=='username'){
			Q_1.value='';
			}
		}
	}
	function blankpassword(){
		with (document.form1SP){
			if (Q_2.value=='password'){
			Q_2.value='';
			
			}
		}
	}
	//-->
	</script>
	<script language='javascript'>
	function disppassword(name) {
  var o;
  if (document.all) {
    o = document.all["mychange"];
  } else {
    o = document.getElementById("mychange");
  };
  if (name == "") name = "&nbsp;";
  o.innerHTML = "" + name + "";
}
	</script>
	<script language='javascript'>
	function disppass(){
		if (navigator.appVersion.indexOf("MSIE")!=-1){
		temp=navigator.appVersion.split("MSIE");
		version=parseFloat(temp[1]);
		}
		else {
		version = 6;
		}
		if (version>=5.5){
		disppassword("<INPUT id=Q_2 type=password name=Q_2 size=11 class=home2>");
		document.form1SP.Q_2.focus();
		document.all.Q_2.focus();
		}
	}
	</script>

After crashing, the crashreport thingy says that it caught SIGSEGV.
Backtrace (from same thingy) :
