Keys don't work properly in konsole

["Felix E. Klee" <felix.klee@inka.de>]

Hi,

on my Potato system with the latest KDE 2.1-installation and the debian
XFree86 4.0.3 packages installed I have trouble with certain key-events
in konsole: even though I selected 
    xterm (XFree 4.x.x)
as a keyboard setting I can't use the begin or end keys. Is this a known
bug in KDE? Are there any workarounds?

TIA,

Felix
