Version:           1.0 (using 4.2.86 (KDE 4.2.86 (KDE 4.3 >= 20090514)) "release 126", KDE:KDE4:Factory:Desktop / openSUSE_11.1)
Compiler:          gcc
OS:                Linux (x86_64) release 2.6.27.21-0.1-default

When I try to change widget style to "other than oxygen", system settings changes the style only for itself. If you close and open system settings, they still have their style changed, but the style combo shows oxygen as set.

Tried to restart apps and to logout/login.
Tried this with new user as well, so it's not an old settings bug.

To reproduce:
1. go to system settings -> look -> appearance -> style
2. change style to e.g. motif
3. open e.g. konqueror
...style is not affected
