yes, the text appears only after successful login

I remember, some time ago, there was a problem that Konqueror switched engines
involuntarily ... probably, this has something to do with it?

it crashes before I have any opportunity to switch the engine for the new
window, if you ask about this

if I switch to KHTML manually in the original window *before* clicking "Platba
do ČR a SR" then it works as expected

they have some demo but you have to register[1] with lot's of personal info ...
probably you can fake it ...

now this may be a clue - if you look at the code, there is:

<a href='dz-filler.cgi?SUBMIT=PREVOD&amp;ID_ucet=...' onclick="okno(650, 450,
'dz_orders')" target='dz_orders'>Platba do ČR a SR</a>

function okno( height, width, cil ) { var w;
    w=window.open ( "/ib/empty.html", cil,
"toolbar=n,height="+height+",width="+width+",resizable=1,scrollbars=1" );
    w.focus(this);
}

now, just a wild uninformed guess, doesn't the combination of using "target="
with a window label that doesn't exist yet together with "window.open" refering
to a blank page trick Konqueror into thinking that it needs to load the
"introductory page" for which, if I get you right, it uses KHTML?

just for comparison, the default blank page gives this source:

<html><head><title>about:blank</title></head><body></body></html>

while empty.html reads:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd"><html><head></head>
<body>

</body></html>
