Version: (using KDE 4.0.0)
Installed from: SuSE RPMs
If I change the toolbar icons size to 32pixels in systemsettings, it makes no difference to the size of the icons in applications.
Confirmed even using current trunk.

I confirm it for 4.2 from Debian Experimental reposotory.
I'll add that the problem is there not only for 32 px icon size, but for any size except the default 22 px size.
Changing the default icon size for toolbars in System Settings doesn't work; whenever I launch an app, its toolbar's icons are 22 px big. It seems that the default toolbar icon size option in systemsettings doesn't have any effect.
If you want to change icon size you have to do it via right click on an app's toolbar and choose the size you want; but there's still a malfunction: icons change, but when you restart the app and icons are again 22 px. This happens with all KDE apps.
As far as I have been able to see, the problem is the "Main toolbar" icon size option in System Settings->Icons->tab "Advanced" (I'm using KDE in Spanish, so excuse if names aren't exactly like I'm saying). Excepting for the default 22 px size, it doesn't respect the size you set, but it does respect any other size you may set; any size but the one you set... crazy, hehe. So at least there's a workaround, till the bug is solved:
For example, if "Main toolbar" icons size in S. Setting is set to 32 pixels, you go to any KDE app, right click on the toolbar, and choose 32 pixels for icons size, when you restart said app icons will be 22 px big again; but if you choose 16 or 48 px, the setting will be respected and when you restart the app, icons will be the value you have choosen. So, if you set the icon size in S. Settings at any value you do NOT want to set for you apps, it will work.
Of course changes for icons sizes have to be done app by app; like I said before "toolbar" and "Main toolbar" icons size configuration in S. Settings don't seem to have any effect.
