I'm running Suse 9.1 and KDE 3.2. I normally do not use Show Device Icons, but 
I tried turning it on to see what would happen. I did not get any errors. I 
noticed on that page there are a whole lot of different possible types of 
devices. Have you tried limiting the selection to only the ones that are of 
interest to you (e.g. you have them installed on your PC). Perhaps you can 
isolate it to just one problem device type.

Also, you should see if there are any clues in /var/log/messages. You say you 
are a newbie so here are specific instructions. You probably have to be root 
to see this file. The normal procedure is to log on to KDE as yourself, so 
that all your activity gets logged as your own. Open up a shell then do 
Session / New Root Console. Enter the root password and you'll have a shell 
where you can do root activities. Then type 

tail -100 /var/log/messages | more

which allows you to scroll through the last 100 lines of this file. Use the 
spacebar to go forward a screen and "b" to go back one screen. To search for 
something (like say "io-slave") type


and press return. You can also do

dmesg | more

and search in a similar way. Hope this helps, let us know what happens.
