the backtrace seems to report a crash while exiting the application. Now, KDE version seems a bit old. Any chance you can test if crash still happens with more recent versions ? (4.9, 4.10 ?) The way StyleHelper is dealt with has changed some in order to hopefully prevent such crashes at destruction.
