probably a dupe. thanks to stupid exceptions we cannot say from this backtrace... or debug to fix it :-(

please try to run kwin from konsole, reproduce the crash and pray for some info on the exception.

otherwise please provide informations about the alt+tab configuration that reprduces this (effect, no compositing at all, tabbox settings etc.)
