KDE: changing PATH for Konsole

[Frans Pop <aragorn@tiscali.nl>]

Hello folks,

I am using KDE from Woody (2.2.25) and can't figure out how to change the 
default PATH for Konsole.

I would like have ~/bin added to $PATH when Konsole starts up, but where (and 
how) do I do that.

I have the following in ~/.bash_profile, but that seems to be ignored by 
Konsole.
<----SNIP---->
# set PATH so it includes user's private bin if it exists
if [ -d ~/bin ] ; then
    PATH=~/bin:"${PATH}"
fi
<----SNIP---->

TIA
