aticonfig --swap-monitor crashes kicker

I have a big desktop configured with 2 monitors and a resolution of 3360*1050.
Sometimes the second monitor is on the left instead of the default on the right. So I use "aticonfig --swap-monitor" to change it quickly. Whenever I do that something crashes. I think it is kicker.
When I do it directly after logging in to kubuntu kicker will restart automatically. If i use it later, when a lot of programs are running I manually have to restart kicker after the aticonfig command.

I don't know, if this is aticonfig related or maybe a bug in kicker or whatever.
My system is up to date with the latest patches.

Here is my xorg.conf and some more info for your needs.
