This is probably a kdelibs general problem.
The listbox showing the different wallpapers in the "desktop activity settings" scrolls a full page when I use the mouse scrollwheel.
This is much too far as the scrollwheel should scroll the view just by a part of the view (e.g. 1/4 or less), otherwise I simply lose track of what I currently see.
Compare the behaviour with other usages of the scrollwheel in KDE and you'll see that the wheel is more for "slow scrolling" but not for pagewise jumps.

Works for me in KDE 4.7.3, do you still experience this problem?
Comment 2 Martin Koller 2011-12-03 20:32:26 UTC 
No, it does not work better in 4.7.3. It is still the same behavior: The mouse wheel scrolls page-wise - the same amount as if you click on the scrollbar area to scroll a whole page.
Interestingly the pageUp/pageDown keys do also not work correctly.
Instead of scrolling a page, they just move the selection 1 element up/down, in the same way as if you use the Up/Down cursor keys.

The problem still exists in KDE SC 4.8 RC2
