Also fixed a little bug in kcmkwincompositing (dropdowns on the general tab were not updated correctly) and cleaned up the code a bit (removed a few unneeded function calls and stale connects).
See the conversation on the mailing list ("Patch for bug 174769", http://lists.kde.org/?l=kwin&m=122696916611602) for further information.
