I am writing about selecting oxygen or qtcurve in kde system settings and after that, new opened windows of dolphin are using the gtk theme, like mist or clearlooks or whatever is set with lxappeareance. Basically the kde/qt apps (dolphin) are using the gtk theme set with lxappearence.
After playing around I noticed that this behavior does not affect other users exept the one created at install, for 1002 1003 seems fine. Don't know what to take from this.
